I have 5 cats in my household. 4 are males. Ages ranging from 2 - 7. 4 are males. The youngest being two and a half. It just cost me $850 with a urinary blockage and crystals. He is on medication currently and vet recommended science diet cd & royal canine so. Both are extremely expensive to feed five cats. Once this particular male cats ailment clears from the meds, can anyone recommend other cat foods. Only one male really eats can food the rest like dry. Dissolving his capsule in tuna fish juice and he is eating. Having read so many comments it seems trying to get them all on can food would be the way to go? I believe it would be less expensive to feed them real tuna than the 3 ounce expensive urinary diet food! I cannot afford the recommended dry foods nor the 3 ounce can foods for 5 cats. I guess I need to discuss cost alternative foods with the vet. I wonder if once my cat's meds are completed and see if just trying to get them all to eat can food would make a difference. I have the filtered water fountain which they all love but a couple just drink the water directly from my purified/ionized swimming pool. Any suggestions until I speak with the vet next week?
