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.
