I honestly don't know why the fuck she was named "Tigger". She wasn't ginger at all (brown tabby with black tabby markings, like any other tabby), and she sure as fuck wasn't the happy-go-lucky character she shared a name with.
Meanest pet I think I've ever seen in my life, and I've been bitten by an ornery cat at a no-kill animal shelter in Utah when I was fifteen, and a larger dog of a random woman I met outside of the Clayton coffeehouse and creperie - which is a fucking awesome place to eat at, by the way - who said he hated children and he bit me when I was eighteen and almost nineteen. If my mom and her sisters - my mom (who is great with animals), her younger sister (who is also great with animals), and her older sister (who is literally the premier crazy cat lady of our entire family) - got scratched and bitten by Tigger numerous times when she was in a relaxed pose and then went crazy as shit on them (and they were older adults at the time) and thought she fucking hated everyone but my grandparents (whom she was still distant from, and she didn't even have the excuse of being adopted after abuse; she was just fucking mean as hell or the hellhounds in hell) - then that means that that cat was absolutely a fucking asshole.
I've seen a lot of dogs and cats, and a lot with behavioral issues (namely, other dogs and other cats), and I've gotten along with almost all of them swimmingly, especially in a controlled, safe environment for them. I don't like to say this of any other dog, cat, or whatever pet animal, and I don't like to call pets "assholes" but Tigger was absolutely the meanest asshole bitch of a pet that I've ever encountered in all of my thirty-five years of life.
