So some of the weight is due to that, but ever since he was neutered about 6 months ago, he has steadily gained weight. Our cats are all fed together (Nutro Choice Complete dry and felix as good as it looks wet), so how can we control his food? Is it ok for all our cats to go on the Nutro Light (as the dry is free fed and is probably the biggest culprit). If anyone can suggest anything other than feeding them separately, it would be really appreciated!! Thanks!
