My 19 year old cat began having reoccurring bladder infections. I used Licks Urinary Tract Care (comes in packets, which I squeezed into her mouth) and HomeoPet UTI+ (10 drops onto her canned food). In addition, I changed her food to Wellness and Purina Pro Plan Focus Urinary Tract Health Formula (both canned and dry food). Much to my surprise  it worked!
