"I have a 3yr old tabby that I adopted from the shelter over a year and a half ago. Since the day we got her, she has been throwing up on a regular basis. The vet said it was likely hairballs so we put her on a hairball treatment plan, including special food. When one brand didn't help, we switched to another for a while to see if it made a difference and nothing worked! A few months ago we adopted a kitten from a friend who had a litter and since both cats were eating out of the same dish, the older cat started eating the kitten food too, but even that was only a mild improvement. Then one day while I was at PETCO, I explained my problem to the service agent and he recommended the Natural Balance Ultra Cat food because not only was it the finest ingredients but because it wasn't formulated for a specific age group. Within a week she stopped throwing up completely, even without the hairball treatments!!!! Thank you PETCO and Thank you Natural Balance!!!"
