From what I have read, Rats eat mice, so I wouldn't recommend putting the two together!
No, you can't.
No, you can't.
It all depends on the breed of hamster. Usually rats tend to be bigger when fully grown than a fully grown hamster. And if its a dwarf hamster the rat is definitely bigger.
If you want them to breed, then yes if not then keep them separated
a rat.
it is very BAD because they will fight most of the time till one dies and they wont breed
The Golden/Syrian hamster is the most popular breed.
You will need to dispose of the hamster's carcass - check with your local trash disposal company or with the local county board of health. Some veterinarians will offer body disposal as well through their facility. In the future, you should keep your rat segregated from other rodents, as the rat has shown it will be aggressive.
Probably a rat, its much bigger and stronger the hamster would be VERY hurt! :(
Non they all fight all hamsters get pregnant by accident and they fight alot my hamster got so hurt when i got another hamster and put her in his cage
No, they will fight
mourn the loss of your hamster.
