I'm so stressed out!! I feed my 11 year old cat natures variety grain free which got rid of his nasty skin allergies and gave him a beautiful coat. Unfortunately he has recently had some issues with cystitis every few weeks but no complete blockages. He is under a vets care and we have a recheck today but he is still having trouble urinating (only gets a tbsp or so out) last time we saw the vet she showed me how to check his bladder to make sure it wasnt blocked so I check it daily. Vet recommended some crappy prescription food and I mentioned my concerns of it being low quality and not grain free, she semi agreed and said we could just add water to his current food or feed more wet food. The process to get him to like the moist dry food or canned food is slow, he is very picky even chicken broth ice cubes in his water didn't make him drink more. My husband is sold on the food because an acquaintance told him how it healed her cat with the same issue. When is it ok to feed crappy food just to avoid worse sickness or maybe death which can happen if he is ever fully blocked? My other thought is to just take him in for IV fluids every few weeks when I notice his urine output decreasing. We were at the vet 2 weeks ago and he got fluids then within a day or so he was urinating normally but yesterday the problem started again. Any other ideas I can bring up to the vet to stop this?
