That's what the vet said too. I never knew they made hair ball food. I guess I just never took the time to look and see what different kinds they have. Today when hubby gets home he and I will have to go to the vet and get the samples and get a bag of food and see how it works. I only want to get the samples of the medication to make sure Cubby will take it with out any trouble. I have never had to give him any kind of medication before so I just want to make sure he will be ok with it. He is out next to me right now trying to get some lovings and everytime I pet him for a minute or so he thinks it's play time.
