I depends on what gender they are. But I think you can get them neutered
A cage.
The rat will more than likely kill and eat it. Rats are predatory species, and will prey on smaller rodents.
you would probably need a medium sized cage for a male rat as they are quite big. but you could get a cage with a few ladders and and a exercise wheel to keep it active.
keep him/her in the cage at all times or lol this is funny put a litter box in there
It all depends on how many rats you are getting. If you get one i think the cage can be a small one but i think it should at least have two levels. I live near a pets mart teat has a small two leveled cage. If you get two rats the cage should around double the size of the one rat cage. And so on. But if you don't understand this then go to the following link: http://www.youtube.com/watch?v=Xqy02HEy2eE If you need more rat info, this lady in the video (the one above) did more videos which i really like. Hope this helped!
You should house your pet rat in a cage with aspen shavings for bedding. A water bottle and a food dish. Don't put the cage in direct sunlight or near any drafts. It is best if you 2 get rats at one time so they can keep each other company while you are not home to play with them. You can put some toys in the cage for your rat to play with. The cage should be 2 feet by 2 feet by 1 foot for each rat you own.
Just use a large bird cage, or a rabbit cage. My rat has a rabbit cage, and she's as happy as can be. My old rat had a bird cage, and he was perfectly fine.
You should not keep a rat and a mouse on the same cage together, The rat will most likely kill the mouse as that is their natural instinct.
If you trained it, you should be able to call its name, so it comes. If not, choose a food your rat like and set it out, keep the cage open so the rat can get in!
since no one has answered you... I thought I would let you know my rat killed and ate my two gerbils. I let her out for a while and she found a way into the gerbil cage and she attacked them. ick. Another rat I had killed it's cage mate (rat).
You can help a rat have a longer life if you keep it healthy (water food exercise) and keep the rat in a clean cage (claening at least once a week)
No. Rats should be in pairs or more. They become lonely and depressed if kept in a cage all by themselves.
