Difficulty: Moderately Easy
Step1
Make sure your rat is comfortable being handled by you before you try to bring him together with another animal. It's important for him to be in a calm, relaxed state when you introduce your rat to other pets.
Step2
Think about the social system of the other pet you are introducing your rat to in order to determine if it's a good idea to even try the introduction. For example, if you own a breed of dog that is considered a hunting dog, there's a good chance that the dog may consider your rat prey which can make introducing your rat to this pet risky.
Step3
Supervise your animals at all times when you introduce your rat to other pets. It only takes a second for the introduction to go bad, so it's very important that you watch the interaction and are ready to remove an animal from the situation immediately if necessary.
Step4
Know when to stop trying to introduce pets. Some animal breeds or personalities may not get along with one another. It's always better to be safe than sorry.
