My male cat, Skylar, has a UTI. I took him to the vet and started his antibiotic on Monday. He has had this condition before and this is the second time it's come back. I have taken him to a more helpful and thorough vet however, this time around. So my question now is how long till the UTI goes away completely? I left him overnight at the vet on Monday so they could get a urine sample and the antibiotic would have a chance to work through his system. When I picked him up on Tuesday, I noticed no more urinating out of the box until I came home from work this afternoon. I saw him attempting to go a couple of times outside of the box. I gave him more of the antibiotic and he seems better. SO with that all said, I am asking for help in terms of what I can do to prevent this condition from returning, and could this be something more *serious*? I have read up a little on that UT disease, or whatever it is called. The vet didn't seem to think that he had this condition, however, I am going to call tommorrow to follow up on the urine sample. I heard that this condition can be changed with food. What types of food do you all feed your kitties? I have been feeding mine Purina and Purina Indoor Formula since they were little but I guess this isn't the bestest of choices...........
