We recommend that you house at least two compatible rats together. They can also be housed in compatible groups. Providing companionship is an important aspect in their care.
Is it better to have 3 or 4 rats?
Even if you're just getting another rat to add to your group it is advisable to go for 2 or more as rats will settle quicker with a friend of there own age (see Behaviour – Introducing rats). It is advisable not to get many more than 4 rats of the same age at any one time.Is it better to have 3 rats than 2?
Rat companionshipRats can be housed in pairs, although a trio or more often live in better harmony as they create their own social network. Pairs of rats can sometimes get agitated with one another and will tend to show dominant behaviour. Time spent out of the cage and fun training can help prevent this.
