Q: We have a 3-year-old Siamese cat who is very vocal. He cries and yowls for something to eat whenever we are in the kitchen and does not shut up until we give him something.
This has become very annoying. We have tried to teach him not to do this by squirting him with water from a water pistol. He does run away as soon as we show him the water pistol and we do not even have to squirt him anymore. But a minute later he comes right back again and does not give up until he gets something to eat.
Is there any other way that we can deter him from doing this?
A: The problem is that you are using punishment to stop the behavior of an animal. In animals, punishment causes fear, stress or sometimes even aggression as it is hard for the animal to understand exactly what the punishment is for. Your cat has no idea why you are spraying it with water. It only has learned to fear the water pistol and has attributed it to just another inexplicable thing that the humans do in his little world.
The best way to modify such behaviors in animals is with extinction. You just have to withdraw all interactions with the cat whenever he yowls for food when you are in the kitchen.
The reason it works is because the cat decided for itself that there is no point in wasting his valuable time by yowling for food when it does not get what it wants. I would even advise you to feed the cat in a different room of the house so that there is no confusion.
Of course, this all sounds fine in print, but it is very hard to do in practice. The whole family has to join together to ignore the cat when he is yowling, and it takes many weeks to accomplish this. If you ignore the cat for 10 days and then on the 11th you give in and feed it just to shut him up because you are talking on the phone or some other reason, then you are back to square one.
Your cat is only 3, and Siamese live a long time as a rule, so it's wise to apply yourself and invest the time and patience needed to make the behavior become extinct.
