i just got a rat...and i really don't know anything about them i only have one but am going to get another one soon.
in her cage i have a salt lick, her house, a platform and a hammock. what else can i put in there?
also what is a bark bites and lab blocks? where do i get it from?
also ants get into her food in the cage does that matter?

with her teeth will they get bigger if i dont have something for her to chew on? is it ok for her to chew on toilet paper rolls?
