nothing
Usually, no. But in extreme situations when the rat doesn't have anything to eat and it's on the point of starvation then it might eat another rat.

You can get a pet rat from most pet stores.
I don't have a pet rat!
I have a pet domestic rat, and i have yet to find anything he WON'T eat. So, in answer to your question their diet is EVERYTHING
In some cases, yes. For example your cat may eat your pet rat or bird.
Rats will eat just about anything, they are omnivores so they love to eat. feeding them wet bread nuts and a variety of seeds will be healthy for their diet. for fluids they should have water in a tiny dish.
Emily Carr had one pet rat.
*gasp* Feed the poor thing! oAo
Yes. But too much of that type of food will make them overweight.
I have pet rats for a long time, and they eat everything, no sauce, mustard,but sausage and tge bread, that's cool
I have never, ever heard such a thing. Rats are very social animals( including being social with other rats). So, no, unless it has some kind of mental illness or something crazy like that, one rat will not kill another and especially not eat it. Actually, if you have pet rats, you are supposed to have two in the cage.
