It's simple, really. I love mice and hate rats.

I try to explain to Max that there are problems with rats that he ought to think about if he wants to stay alive long enough to grow up.

Most of the problems are to do with disgusting diseases but there are other problems with rats, too. Like, droppings, fleas and bad things that famous rats have done in history. Or danger they are to wildlife.

So don't i-gnaw my warning!
