We just found out that Zoe has crystals in her urine, and the vet recommends Royal Canin Urinary SO diet. My question is, will she need to be on this diet for life (she just turned 1 last week)?
I don't have too much of a problem with her being on the diet, but my other cat Cosmo has a grain allergy, so this diet will not work for him.
Any suggestions? Both cats currently free-feed on Natural Balance dry food, and get Science Diet wet food twice a week - I had just started changing the cats to Blue Buffalo wet after I learned of Cosmo's allergy last month...
