How are mice different than rats?

Answer 1

Rats are larger and normally more aggressive. They live a little longer, and can fend for themselves better. When choosing between a pet mouse or rat, think of what you are looking for. Rats are usually with you longer, but are higher maintenance and are bigger. Rats need larger cages, more food, more water and more care. They may also be more aggressive depending on how they are raised. Mice don't need cages as big, and less food, water and care. Though they only live for about 1-2 years.

Answer 2

Mice are often much smaller, and, often less intelligent than rats. Mice also will eat less, and, if choosing between a rat or mouse for a pet, mice are better if you have less space. Rats will often be much larger than rats, taking up more space, and eating more.
