I had a cat that was like that with tuna. He never begged for any other food but he’d try to get that if you had it on your plate. It got to the point where he wouldn’t even bother me while I was making the food, he would just go and wait on the desk where I ate. He never sat there otherwise so he was planning that shit out lol. He also once stole an entire McDonald’s cheeseburger, wrapper, and all and hid under the bed with it like Beans when he was a very young kitten. That thing was bigger than him.
