I love just about anything fuzzy. Dogs are great & generally have a wonderful energy that helps pick me up when I'm down.
I feel a pretty strong kinship with cats, though. I couldn't take my cat Rusty with me when I moved; he's still at my mom's house. Thank goodness she's a crazy cat lady too. Anyway, he's a large (maybe 15-20 lbs) orange tabby, a total sweetie & quite a talker. He'd often hop (no, more like flop) on my chest while I was reclining & purr while he slowly squeezed the air out of my lungs.
I also think rats are fantastic. They're so smart & friendly. I love it when they sit on my shoulder & make kissy/chatty noises in my ear. However, because of their relatively short lifespans & my rather acute sense of loss when a pet dies, it will be a long while before I get anymore. Much as I love them, I have to think of the long-run benefit for myself.
I think I'd like to have a chinchilla someday, & maybe a turtle...even though they're far from fuzzy. They're quite impressive creatures.
We've also had rabbits (love them) ducks, cockatiels, crows (awesome) & hamsters. I raised Columbia sheep in 4-H in high school, we raised chickens for fresh eggs & I once tried my hand at raising a couple turkeys; Xena & Gabrielle. I was looking forward to turkey eggs, but it never happened. They were quite friendly, though. They knew I was mama & followed me around the garden.
Many's the time we'd get our chicks in the spring & have to cover the bathroom floor in newspaper & keep them in there until it was warm enough (or they were big enough) to put them in the coop. Except for the crows (which we did release) & of course my turkey babies, the birds didn't really impress me. The fresh eggs did spoil me a little, though.
I think the farm animal I'd most love to raise eventually would be a pygmy goat (or 2 or 3). Let's face it, sheep are cute but dumb. Goats are cute & smart, but can sometimes be to wily for their own good. I'm hoping that the small stature of pygmy goats would help keep them from getting into too much trouble.
In all honesty, if I ever have some acreage of my own, I could totally see myself taking in half the residents at the SPCA, as well as saving the pet shop rodentia from becoming snake food.
