Ehh, we had mice and rats for a while because our neighbors decided to keep chickens even though they live in the middle of the city. Rodents loved that chicken feed, but when they would chase them out they would just move over to our house.
Meh.
But, I do have a pet fancy rat. She's a little darlin', never bitten anyone, just likes attention.
She likes the taste of toothpaste, so sometimes she'll put her head in my mouth to lick off whatever trace of toothpaste there is. It freaks my friends out, since they don't even like touching her, but it makes me laugh.
