Our cat Skittles got his first UTI at the age of 4.We took him to our vet and they gave him amoxicillian and a steroid shot.After taking all his medicine it reocurred 5 days later again. I called our vet and they gave me more amoxicillian and some amtripline this time.Any other medicines you use for this type of infection. Thanks.
If it is a bacterial infection then antibiotics are the way to go. If your cat has a problem with crystals then a special diet may help prevent this in the future. Usually a Urinalysis and culture and sensitivity will help determine the best course of action. Good luck, vetcare
