One cat I had for years, but never mentioned, is a large black cat named Petey. I lost her to cancer today. She may not have been a cuddly sort, but she was not to blame.
She came from a veterinarian, as Petey's owners had brought her in and asked the vet to euthanize her as they were "tired of her". How does one decide to kill an animal because they're tired of it - especially after having her for five years?
Anyway, to make a long story short, the vet refused to euthanize Petey and called the local cat ladies instead. I took her in and she never left.
Although I never knew exactly what happened to Petey at her former home, except for being declawed, she had developed some emotional issues when she arrived here. She didn't like any other cats and didn't seem to like me either. Instead, she simply hid under the bed, only coming out for visits to the food dish and litter box. She eventually took up residence on the sofa (I'd put a cat bed there for her), but her demeanor didn't change.
During the first years, she displayed signs of what vets call "self mutilating" behavior. She sometimes would lick herself bald in places, and once was so frightened by the sound of a dog fight outside that she got under the guest bed and stayed for days. When I finally found her, she'd been frozen in place for so long that she'd peed on herself and developed a nasty rash called urine scald. I ended up taking her to the local vet emergency clinic.
However, Petey had calmed down some in the last years. She decided that she'd rather hang out in a dog carrier than the sofa, so I fixed one up for her, complete with heated cat bed. The self mutiliating stopped, and she even came out now and again to visit me for a minute or two. The only touch she could stand was a scratch under the chin; anything else and she would go postal. Otherwise, she spent her time asleep when not stuffing herself with food. She gained the nickname The Feline Planet, but since eating seemed to be her only joy in life, I never put her on a serious diet.
Recently I noticed she'd gone off her food, and after three days of antibiotics didn't have any effect, I took her to the vet. It turns out Petey had developed a large cancerous tumour on her belly, and since she was already a big girl, I'd never spotted it. The prognosis was awful. Either I could take her home and watch her suffer and starve to death, or have the vet euthanize her. So I went for the latter.
I spent a few minutes with her before the vet came in with the first shot (she's particularly kind, and sedates before she administers the phenobarbitol). I think I heard her purr a little bit during her last chin scratch.
