Food & NutritionI have a 3 yo male cat who presented with almost complete blockage due to crystals. My vet said that over the counter urinary tract health dry food is okay. My question is: What is the difference between Purina Pro Plan FOCUS and Purina ONE Special C
Hi, thanks for using Boop by Petco! I politely disagree with your Vet. I do not recommend over the counter urinary diets for cats who have been obstructed. It is a life threatening condition and not to mention expensive issue. I wouldn't risk a non-prescription diet. They are not comparable to the prescription options. I recommend, if your cat will eat it, an all canned food prescription urinary diet like Hill's c/d, Royal canin SO or Purina UR. Increase water intake where ever possible (adding water to the canned food, water fountains, etc). If you decide to go with an over the counter option then go with the lowest ash and do all canned food. I wish you the best!
