Sentry Petromalt Hairball Fish

Sometimes, being fishy is a good thing…especially if you're trying to help a very picky cat avoid hairballs! The original formula that cats love! SENTRY Hairball Relief helps relieve the constipation, dry cough and the occasional vomiting associated with hairballs. This product uses Petromalt technology, and is an intestinal lubricant that helps prevent the formation of hairballs and eases the passage of hair that is ingested. It is safe and effective for cats and kittens over 4 weeks of age.
