Most bladder infections are caused by mucus in the bladder. The mucus contains small stones or gravel that irritate the lining of the bladder and urethra. The infectious substance is passed to felines through bacterial agents in food or water sources. If your cat is unable to urinate at all, take it to the vet immediately. This symptom is caused by a urinary blockage which can result in fatality if left untreated. You should take your cat to the vet as soon as possible if you notice any symptoms of a bladder infection.
Instructions
Follow your cat to see where it is urinating. If it typically uses the litter box and has now started urinating outside of the box, schedule an appointment with your veterinarian and have your cat tested for a bladder infection.
Listen to your cat when it goes to use the litter box. If it cries out while he urinates, it should be checked by a veterinarian for a bladder infection.
Watch your cat closely to see if it is straining to produce urine.
Look for small wet spots in the litter box or traces of bloody urine.
Monitor trips to the litter box. If your cat is using the litter box more frequently it should be checked for a potential bladder infection.
