Will My Cat Eat My Hamster? Our Vet Explains

All pet lovers dream of living in a home filled with friendly animals that all happily coexist with nary a snarl, hiss, or growl. Unfortunately, not even domestic pets, big or small, are wired that way. While they’re accustomed to living with humans, they still have the natural instincts that were useful to them when they were fending for themselves. For example, hunting instincts run strong in some kitties.

This means that pairing a hamster and a cat isn’t considered a good idea, as the cat may eat the hamster, if not just kill them. Most cats’ predator instincts will activate when they see a hamster, and most hamsters, as prey species, will get stressed when in proximity to a predator like a cat.

Are Cats Predators to Hamsters?

Hamsters and domestic cats don’t tend to cross paths much outside of human homes, but considering that a wild cat’s diet consists of birds, small reptiles, and small mammals like rodents, hamsters would definitely make the menu if the opportunity arose. While your house kitty is more reliant on kibble than small rodents to fill their bellies, they typically retain that prey drive that makes them enjoy the thrill of the hunt, even if they don’t eat the kill afterward.

Ultimately, some cats may kill and eat a hamster, while other cats will be happy with just the kill. Not all cats are bloodthirsty, of course, as some may not care to exert the effort, but you may never trust knowing which category your cat falls into until they’ve already done the deadly deed.

You may have seen pictures and videos of hamsters and cats cuddling or even playing together. This cute moment to human eyes may be quite different in a cat’s mind. What you perceive as harmless batting or chasing is hunting for the cat. 1 They’re using the play session as a way to hone their hunting skills, using your hamster as prey. Even if a kitty doesn’t go all the way and kill their prey in this game, the thought and drive may be there.

Do Hamsters See Cats as Predators?

Hamsters raised as pets may have never had to dive down into a burrow to escape a predator, but you can be sure the instinct is hardwired into their brains. Being small mammals that eat mostly plant matter, they are accustomed to being near the bottom of the food chain. Their brains are forever attentive to identifying and escaping predators, which can include your cat.

Even if a hamster has never seen a feline before, they may associate the cat’s scent with that danger, likely causing long-term anxiety. Being repeatedly exposed to the sight or smell of felines can prolong that stress, which can quickly lead to a decline in physical and mental health.

So, even though your hamster may stay safely in their cage, having your cat looking in from the outside can be detrimental to their well-being, not to mention the potential dangers should they ever come in contact.

Can Hamsters and Cats Safely Live Together?

Attempting to have a cat and hamster co-habitat is risky for the hamster. Even if the cat isn’t outwardly violent toward them, their mere presence may be doing untold mental damage. Many people claim that they have happy cat-hamster relationships in their homes, with both furry friends able to spend time together safely. This can happen with a cat that’s not overly interested in hunting, but they’re still a significant stress factor for the hamster.

Even if you can give your hamster a dedicated cat-free room, they may not be completely safe. It may decrease their stress levels, but it may not get rid of the anxiety completely, as they may still be subject to that stress-inducing feline scent. Your cat also may not agree to this situation, as they may become curious about what’s behind the closed door, creating a potentially stressful situation for them too.

From a safety and health standpoint, it’s simply better if cats and hamsters don’t live together in the same household.

Conclusion

There’s no way around it: Cats are predators and hamsters are prey. This age-old pairing usually ends poorly for the prey. Even if your kitty doesn’t seem overly aggressive toward your hamster, there is the real possibility that their presence is enough to induce stress effects that can have negative consequences on the hamster’s overall health and happiness.
