When feeding any YA cat food, our clients see few hairballs. We find that YA cat's skin and coats become very healthy which means a lot less shedding. Naturally, less shedding equals less hairball issues. And, due to our specific balance of protein, fat and fiber sources, should hair be ingested, it is more is likely to go through to the litter box. While hairballs won't be totally eliminated, they should occur less frequently.
