Teach your cat to come when called by calling it whatever it was already doing

Cat-training literature exists. It is written by optimists and reviewed by cats.

Call the cat whatever it is already doing. “Sitting! Good sitting.” A 100% response rate, on the cat’s terms, which were the only terms on offer. The cat now comes when called, provided it was already coming. Dominion achieved, nominally. The cat has signed nothing.
