Cats can develop kidney problems from eating a dry food only diet. Since they originated in the desert they are genetically trained to get moisture from their food and only when really thirsty will drink from a water bowl. This is usually the point at which they are already extremely dehydrated.
So if you feed kibble which needs moisture to break it down to digestible form, where do you think it will obtain that? It comes from the cat’s body, which will further dehydrate it. This also stresses the kidneys and over time can translate into urinary tract disease, stones, infections or kidney disease.
If you must feed dry, please make it wet before you offer it to kitty but placing in a bowl of water so it can absorb the needed moisture. While this is not real convenient if you are accustomed to leaving a bowl of food out all day, it will save you vet bills in the long run. Plus a lot of dry food contains grain which is not a normal staple for wild cats. Wet grain-free food is the healthiest for your whiskered family member.
Dogs are better adapted to dry food because they readily drink from a water bowl. But it is still best to feed the wet food or a mixture. Maybe you noticed your dog wolfing food down. This is normal and their stomachs are made for this because in the wild they need to eat and run. But, this wolfing is better adapted to wet food as when fed dry they are five times more likely to bloat.
