My 86 year old Mom has a sweet cat who is great company for her, and we love him so much. But she overfeeds him, and now he's overweight. He was abused about a year ago as a stray, and had his mouth wired back together, so for a long time, he was only able to eat canned cat food. He is healed and able to eat dry food as well, but she is constantly putting a little can of food in his bowl every time he meows at her. He probably eats double/triple what he needs......I'm not sure if she's just giving in to him too much, forgetting she fed him, or what. I've fussed to no avail. Told her his obesity will lead to health issues, but she either doesn't understand or care. I feel her mild dementia plays a role, and impulsive behavior. She lives alone, and I see her once or twice a week. I wrote a note and taped it to the shelf beside the canned food that says "Feed one can in morning and One can in afternoon) - nothing seems to work short of taking away all canned food and rationing.
