We had an old cat when we got a dog. The dog was taught early on that Toby was his elder, and was not to be disturbed. Since Toby remembered the dog
before; it was no big shock to him.
It was always fun to put a large bone on the ground. Toby would slowly walk over to it and sniff and maybe lick it. The dog would wait... until Toby walked away. Then finally the dog would grab his bone.

Veronica, if you're a dog person, get a dog; your kitty won't mind. And
i'm glad you caught the jerks on tape.
