We first noticed the behaviour a few weeks ago and took her to the vet, who diagnosed a UTI and put her on antibiotics and an anti-inflammatory. She continued with the behaviour so I took her back to the vet, who said her temperature was normal and could feel no signs of a UTI. We did a repeat prescription as a just in case, however the behaviour is still continuing. She doesn't seem ill or in pain. We have not had any accidents inside the house, it's just the constant tiny, drippy wees when she goes out. My fear is it is cancer and I am scared to take her for further tests. What should I do?
