I have been trying to get Ziggy to stop chewing the door frame when I leave for work. He is a 6-year-old orange tabby and very food-motivated, but this habit is driving me crazy. I read somewhere that you can use food to create positive associations with your absence.
I tried putting his bowl on the other side of the door so he has to wait for me to come back to get it. But he just sits there looking sad. I have a 2-year-old mixed named Biscuit who is not interested in this at all. What am I doing wrong?
