I see, I was planning on getting a rat from a rescue or re-home ad. I see, I was considering the flying saucer since it looks a bit safer, what about the exercise balls I use to have hamsters so I'm a little familiar. My hamsters we use to put them in an exercise ball. Though I looked on some sites I like Hsus.org for foods they can't have since that concerns me as much as what they can have. Do they require a lot of vet care? I mean if I get two I knowing how to pair them and how much spay or neutering would be. I wouldn't want a bunch of rat babies. I am probably going to wait until a graduate and get a job because it really depends on what kinda job I have if I get any pet, since there is a chance that I could be traveling and won't be able to be home enough to give them the care they need. It would just be stupid. Thanks IRescue, for your help.
