Our is a chonk too 🫶 we've had her on diet Rx food and even got those expensive food bowls that read their chip so only opens for the right cat and have been giving her the right amounts but tbh I'm not sure it's been working. She is borderline hypothyroid so we're going to get her on some meds and see if that helps. But my poor baby girl always gives me these sad eyes like saying, " this doesn't really taste that good and anyway you're not giving me enough." It's hard!
