good afternoon all - looking for some opinions on dry cat food. My youngest boy is currently on Royal Canin's Siamese food, however he is not that wild about it and he is hacking up hairballs. I want to get rid of the breed specific food and return him to an Indoor cat food. His favorite was Puriana Indoor which is probably the worst for cats. I am thinking of going with Nutro. I hear felidae is good but I have to stick with what I can get a pet smart. What you would suggest? Is Nutro good? Thanks
