If you’re a cat person who is interested in becoming a guinea pig person, or vice versa, you may be wondering if it’s safe to bring the two together. Do cats eat guinea pigs? The good news is that many cats won’t eat guinea pigs, and guinea pigs and cats can coexist peacefully while remaining separated, allowing both creatures to get the attention and care they need. However, it’s important to note that there are some risks associated with introducing cats and guinea pigs, so it’s important to research both species AND get to know their individual temperaments before making a decision.

The Risks of Cats and Guinea Pigs Living Together

Although cats and guinea pigs can often get along peacefully, there are still risks involved in bringing them together. Cats, especially if they’re not used to being around guinea pigs, may see the small creature as prey and attempt to chase or even attack it. They usually won’t eat it, but they may kill it if they have access to it.

Guinea pigs are also prone to stress and can easily become overwhelmed when confronted by larger animals like cats. It’s important to keep the two separated and introduce your cat to the guinea pig while the guinea pig is in its enclosure and your cat can’t get to it.

Also, cats can carry parasites that can make guinea pigs very sick. It’s important to ensure that your cat is regularly treated for fleas, ticks, and other parasites before introducing it to a guinea pig.

Making the Decision

Ultimately, whether it’s safe to keep cats and guinea pigs together will depend on their individual personalities. If you have an especially curious or predatory cat, it may be best to keep the two animals separated. On the other hand, if your cats and guinea pigs are both easy-going creatures, they may be able to live together without any issues.

The best way to ensure success is to introduce them slowly and carefully. For example, give each animal their own room and allow them to explore the other’s territory from a distance. This will help both animals become comfortable around one another without putting either of them in danger. If your cat does get close to the guinea pig and seems like it wants to attack it, separate the two immediately.
