Typically a cat with a UTI will pee frequently in small amounts, may stop using the litter box and pee in the house, and may drink an excessive amount of water. The only way to know for sure if Ashton has a UTI is to take him into the vet for a physical exam, blood tests, and a urinalysis. This is confirm the presence of a UTI, and the vet can prescribe antibiotics to treat it. If you think Ashton has a UTI, I would take him into the vet first thing in the morning.

    Hello, sorry to hear about Independence. It sounds like these signs would be more consistent with a UTI. Our biggest concern is that he is unable to urinate by becoming obstructed. Therefore you should monitor that he is able to urinate when he does go to the bathroom. If you notice any signs of straining, such as frequenting the toilet often but being unable to produce any urine or only producing a few drops then you should have him evaluated by a veterinarian today. Other signs include painful urinations which may show through loud vocalizations while urinating, blood or dark colored urine, and lethargy. Again, if you do note any of those, do not hesitate to bring Independence in to your veterinarian. Best of luck and hope this helps.

    Hello, sorry to hear about Dusk. If he is not having abnormal urinations (peeing outside the litter box, having bloody urinations, frequently visiting the litter box, or straining to urinate) then he may not have a UTI. However, if you strongly suspect that he may have a UTI, then it would be best if he is indeed evaluated by his veterinarian. Hope this helps and best of luck.

    Urinating outside the litterbox, bloody or dark coloured urine, foul odour to urine, straining to urinate/inability to produce urine, and decreased appetite are all signs of possible bladder infections. Similar signs can be noted due to crystals in the urine, stones in the urinary tract, or trauma. If you notice these signs, Billy Bob Brosius should be seen by a vet, and if you notice him straining to urinate/unable to produce urine, this is a potentially deadly medical emergency and he should be seen by a vet immediately.
