you shouldnt keep a single rat unless you are gonna spend A LOT of time with it because a lonely rat as far as i know can be very aggressive and depressed.What sized cage would i need for a full grown rat? might be picking one up today and want to make sure that i dont get one thats too small.
Even if you spend a lot of time with it, that's not really good enough. You can't be there 24/7, and you can't provide the kind of interaction another rat can, like social grooming.you shouldnt keep a single rat unless you are gonna spend A LOT of time with it because a lonely rat as far as i know can be very aggressive and depressed.
