We have kittens. A mistake I have noticed is how we fed them. By preparing their food at the same spot in the kitchen, they associate movement to that spot with feeding them. So come running. At least 10 tines a day.
The adult cat associates feeding with the sunroom where we have her stay overnight. Originally that was because we needed her not to wake us in the middle of the night. This was intentional behavior modification to make it easier to get her settled. She makes clear she wants food. I go to the sunroom.
Of late, she resists because she prefers the kitten food. So, I give her treats… in the sunroom.
Most people associate Pavlov and his dog with Classical Conditioning. The salivation is a great image and story.
