This is Stanky!
He is fully grown now to roughly the size of a Chihuahua and he is the perfect mix of Fancy Rat, Kitty, and Gerbil. He's 3 years old and will hopefully live to a ripe old age of 8 years old. To the untrained eye, he could be considered kind of ugly, but personality wins all and his breed age gracefully. He doesn't have any magical powers but he more than makes up for that in being the kind of animal I would actually love to keep and take care of.
Rats are good problem solvers and quite intelligent, so Stanky responds to his name and can figure out how to do stuff when I'm not around. Both rats and cats can be litter trained. Stanky uses a little litter tray in his cage/hut. Rats are also very affectionate if you treat them well and spend time with them. Stanky sometimes lays across my neck with his paws hanging off on either side, chittering happily in my ear.
Cats are very independent, so Stanky isn't sad when I need to run errands or get some work done - I leave his cage open so he can go about his business while I'm at my desk. Cats are also really athletic, and Stanky is no exception. He likes to climb up onto the bookshelves and leap off when you walk past - shocking behaviour at first, but he doesn't scratch much so it's pretty harmless.
Gerbils have strong nesting instincts and love to curl up and sleep and be all cute; and they have big, adorable eyes. Stanky gets some of his cuter, more excitable traits from the gerbil in him.
Gah, I wish he was real. <_>
