When they first meet, there is a huge chance that the cat will be the one that will get scared. They will probably be scared unless the guinea pig is in the cage. They sometimes try to attack the little guinea pig while he’s in the cage.

The cage is a limited space in which the cat may feel safe to attack. Otherwise, if the guinea pig is outside the cage, the cat is most likely to be scared of them.

Should You Let Your Guinea Pig and Cat Play Together?

Firstly, you need to be very careful and watch how a cat and a guinea pig behave when you introduce them to each other.

When you introduce them, you need to protect the guinea pig while slowly introducing the cat to the guinea pig. The guinea pig is the sacred animal in this situation and you need to assure him that they are not in danger.

Furthermore, you need to watch the cat’s reactions as they might be a little violent. If the cat is scratching or trying to bite the little pig, separate them and try to create some boundaries for both of them to slowly make them bond.

Cats are smart pets, and they can fool you very easily. Sometimes they might seem very friendly and one time they might become very dangerous.

Guinea Pigs’ Defending Mechanism

When guinea pigs are attacked, their first reaction is to freeze and this defense can rarely work out. If the danger persists, they will try to flee and that is their only way of surviving.

Guinea pigs fighting back are extremely rare but fighting back for them means chewing or biting their opponent. So, they practically cannot defend themselves if the predator is big enough.

But, if the predator is a kitten then the kitten might get hurt too if it provokes the guinea pig.

What Is the Best Way to Introduce a Guinea Pig to Your Cat

Although properly introducing your guinea pig to your cat will take some time, it will be well worth the effort. Even if you have all of your patience, there’s still a chance they won’t get along.

Thus, the following are some ways you can do when introducing them to each other:

1. Introduce Your Pets to Each Other as Babies

It’s ideal to introduce them while they’re newborns if at all feasible. They are able to get acclimated to each other and form a bond as they grow up together. When your kitten is approximately 10 weeks old, it is the optimum time to introduce it to your cavy.

Don’t worry if things don’t go as planned, and be ready to intervene if there are any symptoms of tension or anger.

2. Don’t Try to Push a Friendship

It’s better not to push a relationship amongst your pets, no matter how much you want them to get along. It may be more difficult for your guinea pig and cat to get along in the future if they’re scared out throughout their first meeting.

3. Keep Hold of Your Guinea Pigs and Cats

It’s advisable to hold your cats while introducing them, regardless of their size. If at all possible, let someone else hold one of the pets while you handle the other. This helps them to become accustomed to one another without becoming stressed. Keep these meetings brief, but do them several times every day.

4. Make Certain You’re Present to Observe

You must be present at all times to monitor. Your cat may be startled and may bite if your cavy makes a sudden activity or noise. 

5. Make a Separate Play Space for Them

It’s advisable to create a shared play space for your pets after they’re comfortable near each other and you’re certain that they can socialize. Because cats and cavies are territorial, provide them with a common play space away from their homes to lessen aggressiveness and stress.
