Urinary Problems in Cats

How to deal with urine marking, litter box issues and urinary infections

By Janet Tobiassen Crosby, DVM, About.com

Cats are well-known for their "urinary issues" -- spraying, marking, urinary tract infections and urethral obstructions. These events may happen once or multiple times, a singular event or related. It is always most important to rule out a medical problem before assuming that your cat is just being "bad" or upset about something. Urinary obstructions are responsible for a wide variety of behavioral signs, and can be fatal in 72 hours or less if untreated, so a veterinary exam is most important.

1. Feline House Soiling Problems

A common question for veterinarians is what to do when a litter box-trained cat suddenly starts urinating and/or defecating outside of the litter box. Urinating outside of the box is the most common complaint. This is a question without a quick, easy answer.

Many factors have to be looked in order to accurately answer this question. First and foremost: is this a medical problem, or a behavioral one? An examination of your cat and a lab analysis on the urine by your vet will help determine the proper course of action.

2. What are the signs seen with a urinary tract infection?

Urinary problems are commonly seen in dogs and cats. Symptoms can range from "obviously sick" to very few signs seen, depending on the length and severity of infection. Being familiar with possible warning signs could help save your pet's life. Learn more in this FAQ entry.

3. Glossary Term: FLUTD (Feline Lower Urinary Tract Disease)

FLUTD was previously known as FUS (Feline Urologic Syndrome). This condition is common in cats, and may be seen as straining to urinate, urinating in odd (non litterbox) places or bloody urine. This condition may be life-threatening, and it is always wise to see your veterinarian immediately before any urethral blockage occurs.

4. Glossary Term: Pyelonephritis

In simple terms, the medical term pyelonephritis means kidney infection. Urinary tract infections are classified as "upper" or "lower". An infection of the kidneys is an upper urinary tract infection, an infection of the bladder and urethra is a lower urinary tract infection.

5. My cat urinated on the bathroom rug. How can I stop this behavior?

Urinating in odd places (out of litter box) could be a medical problem (infection, crystal formation), a behavioral problem, or a combination of both. The goal of this FAQ is to help identify and differentiate feline urinary medical and behavioral issues.

6. Help - my cat is urinating in our bathtub!

From the Veterinary Medicine forum. KERMIT111 asks: "My cat/kitten has developed a strange fixation with voiding in our bathtub. He actually tries to get it down the drain. I've noticed that there's a bit of blood with the feces. We clean out the litter box 3 -4 times daily as we have another cat/kitten in the house. They are both around 7 months old, from different litters, and both from farms. Any ideas?"

10. Quick Tip - Shopping For Cat Litter

Cats on the whole are a sensitive bunch, and have very definite toilet habits. If you are using a litter that "works" (i.e. the cats are using it well), try to stick with it if at all possible. Subtle changes in texture (size of granules), scent, dustiness, or frequency of litter box changes may upset your cat's perception of proper litter box behavior, and this could lead to your cat finding litter box alternatives, such as the laundry room or bathroom rug!

11. Senior Dementia in Cats and Urinary Problems

Some cats will "forget" their years of proper litter box behavior with senior dementia confusion. Inappropriate urination or defecation can be symptoms of many diseases, and should always be checked out first to rule out an infection or impaction (constipation).
