I am considering bringing home a pet rat or two. I have never had any pet beyond a cat/dog before. Im not sure what Im getting into. There is this female rat at work that I love. She is less then a year old. I am considering taking her home as they are getting rid of her (she isnt fertile). How much work are rats? What do you "do" with them? Do they pee/poop everywhere/on you when out? How much light/heat/etc do they need? Do they need compainions? There are baby rats from another female, and they said I could take one of those too. Do rats like companions? Another female? Just not sure what Im getting myself into. I shouldnt have become attached to this rat, but I dont want to see her go. Help!
