Cats groom themselves and this hair that it licked free needs to find it’s way through your cats digestive system and back out. Too much hair or a poorly maintained digestive system can cause these hair to become stuck and matt together causing a blockage. If you’ve ever seen your cat vomit up what looks like a long tube of hair, then this has probably been stuck in their oesophagus or stomach and causing them discomfort. Some hairball cause serious blockages which may require vet intervention.
There are a number of things you can do to help prevent hairballs and help the hair your cat does ingest through their digestive system. First of all you should groom your cat, it’s best to start this while they are kittens but you might not have had that possibility if you have a rescue cat or if they are already an adult but with some patience, positive praise and a grooming brush that suites you and your cat, it can become the perfect time for bonding. Plus you’ll also find that they will be less cat hair around your home too.
