Urethritis is the inflammation of the urethra, the tube leading from the bladder to void urine outside the body. Most cases of urethritis is caused by infection to the urethra but urethritis can also be caused by trauma or an irritant to the urethra.

Most cases of urethritis will clear up with a proper course of antibiotics. If your cat has any trouble with urination take him/her to the vet immediately to be tested for urethritis as well as for more serious problems of bladder stones, cystitis and FLUTD/FUS.

Symptoms to look for:


  • Straining to urinate
  • Difficulty in urinating
  • Frequent urination with little urine
  • Painful urination
  • Urinating outside of the box
  • Blood in the urine


Your vet will check a urine sample for pH, for the presence of infection, and for crystals. The presence of crystals may indicate that your cat has cystitis or FLUTD/FUS. Once urethritis has been determined (and cystitis and FUS/FLUTD has been ruled out) your cat will be put on a course of antibiotics to clear up the infection.

Precautionary measures:

Make sure your cat drinks plenty of water as this will help to flush out any bacteria that could be in the system. Cats, as we all know, can be quite finicky so keep his/her water bowl clean and full. Many cats dislike the taste of plastic so try to keep food and water in porcelain or glass bowls. Keep your cat’s litterbox clean and as free of bacteria as possible. This will help limit the spread of bacteria. Also many cats will hold their urine if a box is not clean. This can also lead to infection. Feed your cat only a high-quality, vet-approved diet that is low in magnesium and promotes good urinary tract health.
