Here's why:
* Predatory instincts: Cats are natural predators, and hamsters are small and vulnerable prey animals.
* Size difference: Cats are much larger and stronger than hamsters, making them easily overpowered.
* Hunting drive: Cats have a strong instinct to chase and kill small moving objects, which hamsters fit the bill for.
Important Note: It is extremely dangerous to put a cat and a hamster in the same space unsupervised. Even if your cat has never shown aggression towards small animals, their instincts can take over, and a tragedy could occur.
To keep your hamster safe, always separate them from your cat.
