Our cat, Muffin, usually stopped doing something bad when hearing "Muffin, No!" He'd obey, but sometimes look at me with what appeared to be a scowl, then he'd grunt in a tone that sounded like "**** you!", and walk off in a huff.I have cat I give so much attention too, shes is pretty much a dog. Follows you around, tries to jump on me. In the beginning it was rough but she is very adept at when I don't like when she does something. She can get guilty like a dog when scolded.
Another word he recognized was "kitty". He heard it the first time when my partner happened to see someone else's cat just outside the window, and called out "Muffin, look at the kitty!" From then on we had to be careful about using that word, because Muffin would rush to look out a window when the venetian blinds were closed, and wind up caught between the slats. They were harmless, as they were made of flexible vinyl, but we still had to extricate him.
