I'd usually watch over Jewel at dinnertime, but when she didn't seem to feel like eating much, I'd put her in my bedroom alone with her dinner and shut the door for a little bit so she could eat in peace if she wanted to - without Milita hovering over her, waiting for her to walk away so she could clean up the leftovers.
Sometimes I could tell when Jewel was done with her dinner because she'd try to bury it. She's actually the only cat I know who has ever done this. Even before she got sick with the chronic renal failure, she'd try to bury her food to save it for later sometimes.
She'd use whatever was around - a piece of paper, a sock, a T-shirt....and if there wasn't anything nearby, she'd start to paw at the rug or the carpet to try to make a hole to bury her food in. It was always so adorable to watch her do that!
Other times, she'd simply walk away from her bowl when she was done. But if she hadn't eaten much of her dinner, I was the annoying mom who followed her around with her dinner and showed it to her a couple of more times to make sure she was actually done eating. Most of the time, if I took her dinner and followed her to wherever she was going, she'd eat a little more for me. She always made it clear when she'd had enough, and I'd wrap up any leftovers and put it in the fridge to feed to her later.
Does your cat have any cute eating habits?
