The Late and Great Ratatouille -- Traveled from Florida to Newfoundland, back to Florida, then to PacNW and then to Alaska -- He died at a state park in Alaska, by a lake, so I buried him up on a hill.
BTW, even the real rat fur comes in several kinds, smooth, longer and semi-curly, plus the hairless (really fur-less because they do have tiny hairs) -- At normal rat temperature of 106*, the hair-less rats feel very warm.
One doesn't need to clean the real rats, BTW, because they clean themselves and each other all the time, even more than cats do.
Ratatouille was quite a looker. And what a travel log he had.
I remember a friend's hairless rat who was quite social. And as a child, my brother had a white rat who could charm the fur off of any mammal.
Rats don't get the credit they deserve.
