We have an old cat- about 15/16 I think, she spends a lot of the time curled up on the radiator, but does go out on the prowl at night.
A cat-loving friend says that she's fat, BUT she's fluffy, so looks fatter than she is IMO. We found that feeding her twice a day resulted in food being thrown up on the kitchen floor, so we feed her three times a day (6 am, 4pm, 10 pm) and give her about 40g of tinned meat each meal plus about 20g of IAMS senior biscuits at breakfast time. She gets water to drink, and the occasional little bit of chicken/ salmon/ lamb.
Cat keeps telling me we are starving her, and she's wasting away, but if she is, it's not obvious.
Are we giving her enough, or too much?
