The lost cat and a jealous dog.

I had a dream that I lost my cat in a parking lot. One day a woman who found it, brings the cat to me. She tells me (obviously lying) that she fed him cookies and milk, liver, and black caviar. The cat keeps running away from me. Since some time have passed from the cat's disappearance, I now have a dog - a big St Bernard, who is trained to put his head on my lap when I tap it. So, I decide to feed the cat and I grab one of those cookies the lady brought with her. The cat is not used to cookies and starts to choke. Finally I pick him up - in that instant, my dog gets jealous and bites the cat by the throat. He won't unlock his jaws no matter what. I try with all my might to unlock his mighty jaws with my hands but I can't.
