Hello, all. I've had Grymmothy since the day he was born, and I've never had issues with this until recently. A few months ago, I kitty-sat for a friend of mine, whose kitty had quite a few bad habits, from pooping outside the litter box to stealing food. Fortunately, Grymm didn't pick up on her bathroom habits, but he's become utterly obsessed with human food. He hasn't been around the other cat in nearly two months, but it seems that during the week we had her around, that was something he fixated on. He's not nearly as much of a nuisance as she was- she would jump up onto counters, DEMAND food off of plates and scratch if she didn't get her way, she even got into the sink to lick the dirty dishes. But we can't eat peacefully with Grymm around anymore. He could have a full bowl of food, but if he smells human food, he'll be right up in our faces trying to steal off our plates. No matter how many times we tell him no, he comes right back. If we put him in another room, he'll scream(like someone's trying to kill him!) and claw at the door, and try to tear up the carpet underneath the door. I can't even give my ten month old daughter Cheerios without him trying to take them from her. I'm at a loss; I don't know what to do. I've found a spray bottle was an effective way to train him for most other things, but with this, he fixates on the food, and is just too stubborn to back off.
Does anyone have any tips? Thanks so much!
