5 Personality Traits of Animal Lovers, Backed by Research

If you’ve ever noticed that animal lover personality traits seem to include warmth, empathy, and a genuine concern for others, you’re not alone — and science may back up that intuition. Many of us have a friend who stops mid-conversation to greet a stranger’s dog, or someone who tears up watching a wildlife rescue video. We instinctively sense something meaningful about people who care deeply for animals. But is there a real psychological pattern behind it, or is it just a romantic idea?

Psychology suggests there’s more to it than a simple preference. A study published in the academic journal Anthrozoös in 2022, conducted by researchers at the University of Zurich’s Department of Psychology, examined the link between personality and compassion for animals across nearly 1,000 participants. The findings offer a compelling look at how our personalities — measured using established psychological tools — relate to how much we care about animal welfare. This article breaks down what the research found, what it means for everyday life, and what animal-loving personality types tend to look like up close.

What Does It Mean to Be an Animal Lover? The Psychology Behind Compassion for Animals

Loving Animals and Acting on It Are Not Always the Same Thing

Most people say they like animals — but their actual behavior doesn’t always match that claim. This gap between attitude and action is one of the starting points for psychological research into the human-animal bond. When you see a stray kitten on the street, you might feel a pang of concern. But do you stop? Do you call for help? Research suggests that the strength of that impulse varies significantly from person to person, and personality plays a meaningful role in explaining why.

We live in a society with a fundamental tension: many people feel affection toward animals while simultaneously participating in systems that use or harm them — from food production to scientific research. This doesn’t make anyone a hypocrite by default, but it does raise an interesting psychological question: what separates the person who feels deeply troubled by animal suffering from the person who feels relatively indifferent to it?

Psychologists define compassion for animals as the motivated desire to reduce an animal’s suffering. It’s not just about thinking animals are cute — it involves a deeper emotional and ethical investment. Research shows that this kind of compassion is not evenly distributed across the population. Understanding what drives it can help us understand ourselves and each other better.

Compassion for Animals Is Measured Across Multiple Dimensions

In psychological research, animal compassion is not treated as a single yes-or-no feeling — it’s measured across several distinct dimensions. The University of Zurich study used 4 separate scales to capture the full picture of how people relate to animals. This multi-layered approach is important because someone might score high on one dimension (say, opposing animal cruelty) while scoring lower on another (feeling a personal kinship with animals).

The 4 key measurement tools used in the research were:

• Animal Attitude Scale — measures general beliefs about the ethical treatment of animals (e.g., opposition to sport hunting or animal experimentation)
• Animal Solidarity Scale — assesses how much a person feels a sense of community or kinship with animals
• Animal-Human Similarity Scale — captures how similar a person perceives animals and humans to be in terms of cognition and emotion
• Speciesism Scale — measures the degree to which someone places humans above all other species in moral worth

By using all 4 scales together, researchers could build a richer portrait of each participant’s relationship with animals. A person who scores highly across all 4 dimensions would represent what we might call a deeply committed animal lover — someone whose values, empathy, and worldview all converge around animal welfare. This multi-dimensional approach is what makes the study’s findings particularly credible and nuanced.

Animal Lover Personality Traits: What the Big Five Research Reveals

The Big Five Personality Model and Its Connection to Animal Compassion

The most widely used framework for measuring personality in scientific research is the Big Five model, and the University of Zurich study applied it directly to the question of animal compassion. The Big Five — sometimes called OCEAN — consists of 5 core personality traits that researchers have found to be remarkably consistent across cultures and age groups. Understanding where you fall on each of these dimensions can offer insight into how likely you are to display strong animal lover personality traits.

Here’s a brief overview of each trait:

• Openness to Experience — curiosity, creativity, and openness to new ideas and perspectives
• Conscientiousness — organization, responsibility, and goal-directed behavior
• Extraversion — sociability, assertiveness, and enthusiasm for social engagement
• Agreeableness — empathy, cooperation, and concern for others’ well-being
• Neuroticism (Emotionality) — tendency to experience negative emotions like anxiety, sadness, or irritability

Research indicates that agreeableness and openness to experience are the 2 traits most consistently linked to higher compassion for animals. This makes intuitive sense: an agreeable person tends to be warm, cooperative, and sensitive to others’ suffering — traits that would naturally extend to non-human beings as well. An open person tends to question hierarchies and explore new ethical frameworks, which may lead them to consider animal welfare more seriously. In contrast, individuals who score high on dominance-oriented or hierarchical thinking tend to show lower empathy toward animals.

Agreeableness: The Strongest Personality Predictor of Animal Compassion

Of all the Big Five traits, agreeableness appears to be the most powerful predictor of how much compassion a person shows toward animals. This trait is often described as the “warmth” dimension of personality — it reflects how much someone prioritizes harmony, kindness, and the well-being of others. Studies suggest that highly agreeable people don’t just limit this warmth to humans; they extend it outward to include animals and, in some cases, the natural environment.

Think about someone you know who is often described as “a good listener,” “always caring,” or “the kind of person who would never intentionally hurt anyone.” That person likely scores high on agreeableness — and according to the research, they’re also more likely to hold strong pro-animal attitudes, feel solidarity with animals, and reject the idea that humans are categorically superior to other species.

What’s particularly interesting is that agreeableness predicts animal compassion even when researchers control for other factors. This suggests it’s not just a byproduct of being generally “nice” — it reflects a specific way of processing the world that extends moral concern beyond the self and beyond one’s own species. People with high agreeableness tend to:

• Feel genuine distress when witnessing animal suffering
• Actively support animal welfare causes or policies
• Perceive animals as emotionally complex and deserving of consideration
• Reject frameworks that place human interests automatically above animal interests

In summary, agreeableness functions like a moral amplifier — and for animal lovers, it tends to point that moral concern toward the welfare of all living creatures, not just people.

Who Is Most Influenced by Friends? 5 Key Research Findings

Openness to Experience, Interpersonal Values, and the Broader Personality Profile

Beyond agreeableness, research suggests that openness to experience and certain interpersonal values also play a meaningful role in shaping animal lover personality traits. Openness to experience is defined as a broad trait characterized by intellectual curiosity, creative thinking, and a willingness to engage with ideas that challenge conventional thinking. People high in this trait tend to question established social norms — including norms around how animals should be treated.

The University of Zurich study also looked beyond the standard Big Five to include interpersonal values — essentially, what people want from their relationships and how they tend to behave toward others. Key interpersonal values associated with higher animal compassion include:

• Valuing warmth and nurturance — a desire to be caring and supportive in relationships
• Low dominance orientation — a preference for collaborative rather than hierarchical relationships
• Emotional openness — comfort with vulnerability and emotional expression

Interestingly, the research also examined problematic personality features — traits that can create difficulties in relationships and daily life. People who score high on traits like callousness, grandiosity, or manipulativeness tend to show significantly lower compassion for animals. This adds another dimension to the picture: it’s not just about positive traits like empathy, but also about the relative absence of traits that involve treating others (human or animal) as tools or resources.

Taken together, the research paints a coherent portrait: the typical animal lover tends to be warm, curious, emotionally open, and oriented toward equality rather than dominance in their relationships.

Gender & Age Personality Differences: What Makes Men & Women Unique?

How the Study Was Conducted: 992 Adults, Broad Demographics, Rigorous Measurement

Nearly 1,000 Participants from a Wide Range of Ages and Backgrounds

The University of Zurich study was conducted with 992 adult participants — a sample size large enough to produce statistically reliable results. The survey was administered online, which allowed researchers to gather data from a diverse group of people efficiently. Out of an initial pool of 1,014 participants, 22 were excluded due to failures on attention-check questions or incomplete responses, leaving 992 valid data sets for analysis.

The gender breakdown was notably balanced:

• 498 women
• 481 men
• 13 participants identifying outside the gender binary

The age range was broad — from 18 to 85 years old — with a mean age of approximately 45.4 years and a standard deviation of 16.5 years. This wide distribution means the findings are not limited to, say, college students (a common limitation in psychology research). The racial composition of the sample also approximated general population distributions, with approximately 782 white participants, 125 Black participants, and 62 Asian participants, among others. This diversity strengthens the generalizability of the findings across different backgrounds and life experiences.

Multiple Validated Tools Were Used to Measure Personality and Animal Compassion

The study’s methodological strength lies in its use of multiple validated psychological instruments to measure both personality and animal compassion from different angles. Rather than relying on a single questionnaire or self-report measure, the researchers combined several well-established tools. This approach reduces the risk that results are driven by the quirks of any one measurement method.

For personality, participants completed questionnaires measuring:

• The full Big Five personality traits (with facet-level detail, meaning each of the 5 traits was broken into more specific sub-dimensions)
• Problematic personality features (traits associated with difficulties in interpersonal functioning)
• Interpersonal values and problems (approximately 64 items assessing how people approach and experience their relationships)

For animal compassion, the 4 scales described earlier (Animal Attitude Scale, Animal Solidarity Scale, Animal-Human Similarity Scale, and the Speciesism Scale) were each administered with approximately 6 or more items per scale. This comprehensive measurement strategy allowed the researchers to identify not just whether personality and animal compassion are related, but which specific personality dimensions are most predictive — and that’s where the findings become especially useful for understanding pet owner personality and the broader human-animal bond.

Practical Implications: How to Leverage (and Balance) Animal Lover Personality Traits

Strengths to Recognize and Build On

If you identify strongly with animal lover psychology, the personality research suggests you likely have a genuine set of interpersonal strengths worth recognizing. High agreeableness and openness — the core traits associated with compassion for animals — are also linked to more cooperative relationships, greater creativity, and stronger social bonds. Understanding these strengths can help you channel them intentionally.

Here are 3 key strengths and how to make the most of them:

• Deep empathy: You likely pick up on emotional cues from others — human or animal — faster than most. Use this in caregiving roles, counseling, teaching, or any profession requiring emotional attunement. The key is to consciously engage this sensitivity rather than letting it overwhelm you.
• Ethical curiosity: High openness means you’re naturally inclined to question whether current systems treat all beings fairly. This makes you well-suited to advocacy, research, or community leadership around animal welfare or related causes.
• Relationship warmth: People with these traits tend to build genuinely nurturing relationships. In personal and professional settings, leaning into this warmth — while maintaining healthy boundaries — creates lasting trust.

Potential Blind Spots to Watch Out For

Every personality profile has its shadow side, and the traits associated with animal lover psychology are no exception. Research suggests that highly agreeable individuals can sometimes struggle with setting limits, saying no, or prioritizing their own needs. The same empathy that makes you attuned to animal suffering can leave you emotionally drained when repeatedly exposed to distressing content or situations.

3 areas worth monitoring:

• Compassion fatigue: If you’re regularly exposed to animal welfare issues — whether through rescue work, social media, or news — the emotional weight can accumulate. Build in deliberate recovery time and set boundaries around content consumption.
• Difficulty with conflict: Highly agreeable people sometimes avoid necessary confrontation to preserve harmony. Practice assertive communication so that your warmth doesn’t come at the cost of your own well-being.
• Over-identification with others’ pain: The ability to feel what animals (or people) feel is a gift — but it becomes a liability if it prevents you from taking action. Pair emotional sensitivity with practical problem-solving strategies to stay effective.

The goal is not to suppress these traits, but to manage them wisely. Understanding the psychological roots of your empathy and compassion gives you more agency over how you express them.

Frequently Asked Questions

Are people who love animals really kinder to other humans too?

Research suggests there is a meaningful overlap. People who score high on compassion for animals also tend to score high on agreeableness — the personality trait associated with empathy, warmth, and concern for others. This indicates that the kindness directed toward animals is likely part of a broader interpersonal orientation rather than an isolated feeling, meaning animal lovers may genuinely tend to be more considerate toward people as well.

Does owning a pet change your personality over time?

Studies indicate that pet ownership can foster traits like responsibility, empathy, and emotional regulation, particularly in children and adolescents. For adults, the effect tends to be more modest, but caring for an animal can reinforce nurturing behaviors and provide emotional stability. It’s likely a two-way relationship: agreeable, open people are drawn to pets, and caring for pets in turn supports those same qualities.

What personality traits are associated with NOT liking animals?

Disliking animals doesn’t automatically indicate negative personality traits — past trauma, allergies, or cultural background can all play a role. However, research suggests that individuals who score high on traits like callousness, dominance orientation, or speciesism (the belief that humans are categorically superior) tend to show lower compassion for animals. These are tendencies within populations, not judgments about individuals.

Is animal lover psychology different from general empathy?

Animal lover psychology overlaps significantly with general empathy but is not identical to it. General empathy refers to the ability to understand and share the feelings of other humans, while compassion for animals specifically involves extending moral concern beyond human boundaries. Research suggests that both draw on agreeableness and emotional sensitivity, but compassion for animals also involves beliefs about human-animal similarity and resistance to hierarchical thinking.

Do animal lovers make better romantic partners?

While no research directly measures romantic compatibility through animal preferences, the personality traits associated with animal compassion — high agreeableness, emotional warmth, and low dominance orientation — are generally associated with more satisfying and stable long-term relationships. People with these traits tend to prioritize their partner’s well-being and communicate with empathy, which are strong foundations for healthy partnerships.

Can someone be an animal lover without owning a pet?

Absolutely. Animal compassion is a psychological orientation — a set of values, attitudes, and emotional responses — that exists independently of whether someone owns a pet. Life circumstances such as allergies, housing restrictions, or lifestyle constraints may prevent pet ownership, but compassion for animals can still be expressed through advocacy, volunteering, dietary choices, or simply supporting animal welfare organizations.

Which of the Big Five personality traits best predicts animal compassion?

Research from the University of Zurich suggests that agreeableness is the strongest Big Five predictor of compassion for animals. This trait captures warmth, empathy, and concern for others’ well-being — qualities that appear to extend naturally beyond humans to other species. Openness to experience is the second most relevant trait, reflecting the intellectual and ethical curiosity that often underpins pro-animal values.

Summary: What Animal Lover Personality Traits Tell Us About Human Nature

The research is clear on one thing: how we feel about animals is not random. Animal lover personality traits — particularly high agreeableness, openness to experience, and interpersonal warmth — appear to form a coherent psychological pattern that connects how we treat animals with how we relate to the world around us more broadly. The University of Zurich study, drawing on nearly 1,000 participants across a wide age and demographic range and using 4 distinct animal compassion scales alongside the Big Five model, provides some of the most comprehensive evidence yet that animal compassion is a window into deeper aspects of character.

This matters because it reframes what it means to love animals. It’s not a quirk or a soft spot — it may be an expression of some of the most prosocial, empathetic, and ethically curious dimensions of human personality. Whether you’re a devoted pet owner or simply someone who pauses to notice the birds outside your window, these traits are worth understanding and cultivating.
