I have two-year old female cat who has recently been diagnosed with Urinary Tract Disease. The doctor wanted her to start eating Prescription Diet but she absolutely would not touch it. She will however eat Purina Special Care for Urinary Tract Health. Is this food providing her with proper nutrition? I have read the thread on "What to feed your cat" but I am afraid to feed her any raw meat as I do not want her to get sick again. Any advice?
