Primate Pet-Keeping: New Study Shows Cross-Species Bonds 2026

Primate pet-keeping is not just a human quirk, according to a new study from the University of Oxford. The research shows that our closest relatives also form intense bonds with animals of other species, challenging the idea that such cross-species affection is uniquely human.

The study, which analyzed 303 cases from scientific literature, 58 photos and videos, and a survey of 66 primatologists, found that primates often care for or interact with animals from other species. This behavior is widespread but varies by age, sex, and species.

Why Primate Pet-Keeping Matters

Understanding why primates bond with other species can shed light on the origins of human pet-keeping. It also raises questions about empathy, social cognition, and the flexibility of animal behavior.

According to the researchers, most cross-species relationships occurred between different primate species. This suggests that primates are more likely to extend care to those that are somewhat similar to them.

Key Findings from the Oxford Study

• Primates frequently form bonds with animals of other species, but the behavior is not uniform across all ages or sexes.
• Most documented cases involved interactions between different primate species.
• The study combined literature review, media analysis, and expert surveys to capture a wide range of behaviors.
• These findings challenge the notion that cross-species pet-keeping is exclusively human.

What the Study Revealed

The researchers examined 303 cases from the scientific literature, 58 photos and videos, and surveyed 66 primatologists. They found that cross-species care is relatively common among primates.

However, the behavior is not evenly distributed. For example, it may be more frequent in certain age groups or among specific species. The study highlights the need for further research to understand the underlying mechanisms.

Implications for Understanding Animal Behavior

This research expands our understanding of animal relationships and empathy. It suggests that the capacity to care for individuals of other species may have deep evolutionary roots.

For pet owners, it reinforces the idea that bonding across species is not a modern human invention but a natural phenomenon with parallels in the animal kingdom.

What to Watch Next

Future studies could explore the neurological and hormonal basis of cross-species bonding in primates. Comparative research with other animals might reveal how widespread this behavior is.
