Need help choosing a cage?
Rats need 2.5 cubic feet of space - per rat!
** We use 2.5 cubic feet as the minimum standard for 1 important reason: since rats cannot fly, they do not use empty air space. 2.5 cubic feet may include shelves, hammocks, tunnels, toys, and some empty space. Anything less may result in territorial aggression.
Creating an enriched environment for your rats begins with a suitable cage. For help choosing a cage, visit our Cages page - HERE.
Find out if your cage is suitable by entering the information below. Measure your cage in inches.
This cage calculator was specially created for myratfriends.com in order to provide a free resource for fancy rat owners. While you may understand your rat's needs best, this calculator serves as a standard guide for comfortably housing multiple rats.
