Symptoms of Hairballs in Cats

Symptoms of Hairballs in Cats

It can be disturbing to watch (and hear) your cat eliminating a hairball. Some common hairball symptoms include hacking, gagging, and retching. Usually, your cat will then vomit the hairball in relatively short order.

If you notice the following hairball symptoms, be sure to contact your veterinarian, as they could indicate that a hairball has caused a potentially life-threatening blockage:

*Ongoing vomiting, gagging, retching, or hacking without producing a hairball
*Lack of appetite
*Lethargy
*Constipation
*Diarrhea
