I have a long haired cat that has always had hairball issues. Also, recently my cat had a very bad episode that led us to the vet. He was hacking like he does when he has hairballs, but there was a lot of pain and pain cries that he was having. We had to rush him to the vet and they were unable to put an exact cause on what happened, but the Vet highly recommended we change his food to Nutro b/c it was very healthy for him and sensitive on the stomache. On top of all that, it also has reduced his hairballs. It is a great choice for pet food and I highly recommend it to other cat owners.
