I know you've mentioned Schumi and the cat to me before. Is there any way to setup the house so that, at least for starters, the cat has a "safe" zone? For example, at our house the basement and the dinning room are "safe". There's a cat door (the kind with the swinging flap) in the door to the basement, and all the cats' food and litter boxes are down there. Absolutely no dogs are ever allowed in the basement. The door is shut, unless I'm doing laundry, and they know better than to move farther down than the first step! The dinning room is gated off, so *if* there is some sort of chase, the cat can go over or under and immediately be safe. Also, while I'm not home, I gate off the base of the stairs to the upstairs, so my cats can sleep on our bed. At night we switch, the cats are out and get the entire house, the dogs sleep on the floor of our bedroom.
I tried a lot of things on Coke and Nikon, trying to get them uninterested in cats, but what it really came down to for us was the cats just getting comfortable around dogs and not totally FREAKING OUT anytime they saw a dog. Before, the cats would see a dog, their eyes would bulge, their hair would puff out, and they would RUN wildly all over. No training I can do can make THAT not look like fun for a dog, and I don't blame them! After a long period of the cats having their "safe zones" and not being forced to interact with the dogs.....
This cat actually rubs her cheeks on the dogs' faces!
Notice the position of the cats relative to the dogs
The cats have learned to just hold their own, and generally if they tell the dog off rather than run, the dog leaves.
