I bought a different brand of cat food a few days ago and I've noticed a change when cleaning the litter. It doesn't smell as bad and and it's not as loose. It's healthier. I bought the food for the female cat TigerLily that I adopted and her kittens but I've also got a male cat (havnt been able to think of a name for him yet) and I've been feeding the food to him as well. It's especially made for nursing cats and their kittens and it's quite expensive. I need to find a good quality dry food that I can buy in large bags that will keep the smell down but isn't too expensive. For the boy and Lily when the kittens are weaned. I feed them wet food every day too but he is now eating only dry food.
