When I was a kid, we had a Collie, Major, and when he was old, my mom got a Siamese kitten. Poor Major was so nice to that kitten. Major would lie down and the kitten would curl up inside Major's legs, which was cute, but then he would start grooming Major's paws, and Major would give us a "long-suffering look", get up and move away to lie down somewhere else. Then it would happen all over again. The kitten would continue until we picked him up and diverted his attention.
My Elkhounds didn't play with the cats, but they loved to watch the cats play inside grocery sacks, etc. My Schipperke, Shadow, would break up cat arguments, at least those with his favorite cat, Cupcakes (also black like my Schip). Shadow would give a body block to the other cat that was arguing with Cupcakes – never did it to Cupcakes.
Squirt followed me home when I was walking Shadow. One of my cats was lying in the front yard, and Squirt walked by her without even giving her a glance -- passed the cat test. Tater was cat-tested by my male cat, Blackjack, when he came as a foster dog. Blackjack walked towards Tater until Tater stepped backwards two steps. Then Blackjack stepped forward again, and Tater backed up again. Blackjack then turned around and walked off, as if to say "You passed the test, you can stay."
I've scheduled an appointment with the behaviorist/trainer, and am adding a new technique to the desensitization sessions - giving yummies when Honey "looks at" a cat. Cats = receiving yummies. Honey liked today's session.
I appreciate hearing all the stories and tips, especially the "happy ending" stories! Thanks!
