Bring home companions who already know each other
A beginner has an easier start with compatible same-sex rats who already live together. They arrive with a familiar companion and you get time to learn their individual habits before making a difficult introduction.[1][2]
Ask where they have been living, what they eat, who they share space with and whether anyone has recently shown respiratory signs. Use the first few days to listen and watch instead of expecting instant handling.[2][3]
Finish the cage before the rats arrive
Choose a ventilated, escape-proof cage with a solid floor. Merck warns that wire mesh can hurt rat feet, while wood absorbs urine. Those details are easier to get right before you are responsible for live animals.[2]
Add hides, paper, hammocks and routes to climb. RSPCA care guidance describes rats as active nest builders, so a cage with choices gives a new group something familiar to do while they settle.[1]
Know the changes that call for help
Rat respiratory disease has several possible causes. Veterinary literature lists early changes such as less appetite, lower activity, weight loss and red staining around the eyes or nose among the signs worth taking seriously.[3]
You do not have to diagnose the problem at home. Learn what normal eating, breathing and activity look like for your own group, then contact an experienced veterinarian when a change persists.[3][2]

Set up one safe shared cage for the pair, then let them settle into each other and the new space at their own pace.[2][1]
A fit for a beginner who can ease in
Settle the home before you ask for trust
Companions, a ventilated cage, nesting options and a veterinary contact are the beginner essentials. Once those are ready, the relationship can start without a rushed first week.[2][1]
