My female cat had a UTI for which she received medication and it went away. A few months later, it came back. Another visit to the vet and an x-ray revealed that she had tiny crystals in her bladder (not stones), which required a different kind of medication. In the meantime, my cat was urinating on her bed, as well as in her litter box. I have washed the bed numerous times, along with her blankets, and have used water and vinegar, to no avail. I was told to get a commercial urine remover, but it's an informational nightmare trying to figure out the right way to go. Some say enzyme removers are best, while others say they do nothing. I'm really in the dark here and would appreciate any help.
