I trained my cat to come to a specific call when it is dinner-time. His name is Schrodinger, usually just ”‘Dinger”, but when it’s dinner-time, I call “SCHRO-DING-ERRR!” all sing-song-y. Every time he was fed as a kitten, that call went out before I put food down in front of him.
Eventually we moved somewhere that we are technically not “supposed” to have an animal, but allowing Dinger to spend most of his time outside, we get away with it. When I don’t know where he is, I can stand at the front door and cry “SCHRO-DING-ERR!” and he comes bounding home looking for a piece of fish or something.
Besides, as soon as the kitty knows you feed it, you’ll have a hard time getting rid of him. ^_^
