When are mice full grown?

Answer 1

Age When Full Grown
I read an article where they claim that a rat is fully grown at 2 months, this may be the age when they become adults, but in my experience rats stop growing 4 months, unless you count pudge..which I don't.

Hi this is Claire Ewing and if you have a rat, it might stop growing at about one year old. Mine is almost one and is still growing. She'll be one in two months. So rats can actually keep growing until the three years old. That's very close to when they're old enough to die.
I know I'm going of the question ,but its very very very very sad when you have something (like a rat or hamster) that you love and want forever dies. I hope you don't go through anything like that.
