Royal Canin Feline Health Nutrition Persian 30 Formula Dry Cat Food

I have two Persians and they are quite a chore on upkeep. Well the little boy developed a urinary tract infection last year (a common occurence in persians), so the vet recommended this food, I had used Science Diet or Iams up to this point and had overall been really happy with them. The vet explained that she thought the simple change in the food might help him, she said that all three of those foods were really the best on the market and he probably just had trouble with digesting certain ingredients in the food. So I changed to the Persian 30 and have been very happy, his infection cleared up and both of the cats have experinced less coughing up of hairballs. one other benefit I have noticed is the litterbox smells less.
