My cat, Boojum, was an “evil” kitten. I have several friends who call him “devil cat” even though now that he’s 10 he’s mostly just aloof… as long as you don’t try to make him do anything he doesn’t want to do.
Of course, I had to pick the kitten that was sleeping at the apex of the pile of kittens inside the cage, and the first one to come and see who was disturbing their group nap. If I had known I was going to get an aggro 20-lb alpha male, I would have selected one of his sisters.
When I brought him home he was about 8 weeks old, and apparently had been in the shelter for a while, because he’s all black, and it was two weeks after Halloween… I’m certain he’d been there at least a month, and his only contact with humans was with hands reaching into the cage to do whatever - feed, clean… grab!
It took me many months to figure out that connection. He was traumatized at some point by somebody’s hands. When I got him from the shelter, there was tape around his neck instead of a collar. That alone could have done it… but I’m pretty sure the formative weeks spent in the shelter cage were the clincher. (I sometimes have to board him at the vet, and it breaks my heart to take him back to a cage.)
As a kitten he was extremely aggressive, and particularly prone to fear-based aggression. The first few weeks, he was constantly biting and scratching my hands. As he got older, he’d run from across the room to pounce on my hands. I couldn’t play with him with most toys, because he’d just attack my hands. I’d be getting ready for work in the morning, walking back and forth between the bathroom and bedroom, and instead of attacking my ankles like most normal 6-month old kittens, he was leaping for my hands.
When he shredded a pair of khaki pants (!!) doing that, I got him fixed the next day. And it still took two years for him to calm down enough so that I didn’t regularly have to soak him under a cold shower to assert my dominance upon him. (Spray bottles? Heh! They didn’t phase him one bit. They just pissed him off… and the vet’s advice was to find something that got the “bad kitty” message across, something other than striking him. It turned out to be showers.)
But by the age of three or four, Boojum, is a stable, intelligent, healthy, indoor-outdoor cat that is sometimes affectionate. His biggest behavioral problem is where he leaves his furballs (in my bed).
It sounds to me, Vinnie, that your new kitten had a comparable experience in the shelter, and is reacting similarly. She is going to be particularly afraid of hands for a while. Explain this to your wife and make her leave the cat alone for a few days while it gets used to its new surroundings.
It’s important to let the cat get used to your household on its own terms. Try to keep the house calm, quiet and uneventful, but don’t avoid any regular noises, like TVs, radios, dishwashers, etc. All of that is good advice in general when it comes to any new cat. Just go about your life and let her get used to the place by herself. Cats hate change, it really stresses them. Especially total changes in their environment. Your wife’s behavior is just adding more trauma to the most psychologically stressful thing you can do to a cat.
If your wife wants to imprint on the cat, I have two suggestions: first, let her become the source of food. All cats respect the food person. Well, at least when they’re hungry they do. In short order your new kitty will be best freinds with Mrs. Virginslayer.
Second, once the cat gets used to the new home, have her socialize with the cat when kitty is not on the floor, experienceing this towering giant leaining over or crawling across the floor to her. Place the cat on a countertop, or on some stairs, or take kitty to bed with you and crawl under the covers.
And the last thing to do is to drag her from hiding spaces. Let her be and she’ll come out when she’s ready. And when she does come out, don’t react by approaching her. Don’t even look at her. If you do look at her, blink frequently and don’t show your teeth. Speak in soft, high pitched, reassuring tones. A direct gaze is a threat in cat body language.
Overall, cats are naturally aloof and independant. Work with it - don’t fight it.
