Here's why:
* Predatory instincts: Cats are natural predators with strong instincts to hunt and kill small animals. Guinea pigs fit the bill perfectly.
* Size difference: Cats are significantly larger and stronger than guinea pigs, making them easily overpowered.
* Playful aggression: Even if a cat doesn't intend to harm a guinea pig, their playful nature can involve roughhousing that could seriously injure the guinea pig.
It's never safe to leave a cat and a guinea pig unsupervised together. Even if your cat has been friendly with other animals in the past, you can't be sure how they will react to a guinea pig.
If you're considering getting a cat and a guinea pig, it's essential to provide separate, secure spaces for each animal. They should never be left alone together.
