My cat Gracie we found is a diabetic since the end of December of 2016. Well two weeks ago took her in she had a UTI again. She had one several months ago. Well she still has stuff in her urin so she has to go back for another antibiotic shot. More money. Why does she keep getting UTI? I don’t have the money to keep having her tested for her glucose levels & UTI. The vet is wearing us out with money. What are we doing wrong at home with the food?
