I have been treating my cat that was diagnosed with cystitis/struvite crystals with cranberry extract, vitamin C, and muti-vitamins. Also feeding Wellness brand cat food. No dry kibble when I am home. The problem still remains what can I leave for a 1-2 day period for all 3 cats to eat when I cannot be home? The vet prescribed Restricted Calorie dry to feed them all the time to correct his cystitis. I have not been doing this as I believe dry food is a contributing factor to his illness and I only feed them this because I have to leave something for them to eat if I will not be home for 2 days. However, I am finding out that he seems to be worse (blood in the urine, straining and many visits to the litterbox) when I return after 2 days of just eating dry. On the other hand, his condition seems to improve when I am at home feeding him Wellness canned and mixing in cranberry, vit. C and vitamins and no dry at all. I am looking for suggestions as to what food I can leave out that all 3 cats can eat. I looked at an auto-feeder that keeps canned foods fresh but with 3 cats i can't be sure that all of them will get to eat. Also I am trying to find a homeopath vet in my area and have not had any luck. Cleveland, OH or even Youngstown, Warren, Ashtabula County areas. Any help/suggestions are appreciated. He is not in pain outside of the litterbox and he is very active, looks healthy, etc. He has a normal appetite, drinks plenty of water. I am up everytime he's in the box so I know exactly what's going on with him and I feel bad that he has to be uncomfortable at all. There has to be something more I can do.
