A few months ago my cat was suffering from kidney stones and a stricture in his urethra. They did a surgery to remove his gentiles so he could urinate, but he was put on Hill's Prescription Urinary Diet to take care of any future kidney stones. He was overweight, so the vet recommended on can per day. Half in the morning, half at night. He is much too thin now so I looked up on the Hill's website how much a cat of his size should eat. At his healthy weight, he is supposed to be 23 pounds. When he was overweight he was 31 pounds. He now weighs under 15 pounds. They recommend a cat that is 18 pounds eat 2 and 1/3 cans per day. That would be, on a 30 day calendar, 75 cans per month for my boy, as he would need 2 and 1/2 cans per day. I already pay about $50 a month for cat food, but if he needs to more than double his intake to be healthy, I would have to pay $150 a month for him to continue on this food. I'm a full time college student who isn't working. I can hardly afford the $50, but to think about $150 is an actual nightmare. He is 13 years old, I'm wondering if I could do anything else to keep him happy and healthy? I absolutely want the best for him, and I WILL pay the $150, but I could really use another solution if possible. Are there any other cat foods that would be safe for his diet? I am only feeding him wet food now, and I add water to it. I will continue to add water to his meals to ensure he is staying hydrated. I am also thinking about making his meals from scratch. I don't know what ingredients to use though, or if that wouldn't be safe for him. Purr-C would very much appreciate some dinner ideas! It is his favorite time day other than bed time cuddles.
