Indoor and outdoor cats have identical nutritional needs, but their different lifestyles can impact their diets. For example, an indoor cat may be less active than an outdoor cat, in turn burning fewer calories. If you notice your indoor cat is a bit overweight, talk to your vet to find the best food to help manage their weight.
Indoor cats tend to spend a lot of time grooming themselves, which could increase their chances of getting hairballs. Some brands, like Hill’s Science Diet, offer special formulas that help control hairballs.
