Feline Urinary Infection

"Feline urinary infection (UTI) is caused by bacteria that enters the body through the urethra, which is at the point where urine exits the body. Bacteria can move up the urinary system and then infect the bladder. Symptoms are sometimes non-existent and are due to the inflammation that accompanies the infection. UTI is usually not seen in cats under the age of 10. Treatment is with a 10 to 14 day course of antibiotics."

Feline urinary infection (UTI) affects between 1% and 12% of cats. Infection is found in both the upper and lower urinary tract. It is often the case that infection that begins in one part of the urinary tract infects the other parts as well.

Infections are caused by both bacteria and fungus. eColi is the cause in approximately 46% of cases and Staphylococcus spp. in 9%.

Cats have a significant amount of bacteria where urine exits the body. If the bacteria, after entering the body,  travels from the outside to the bladder then an infection forms.

Risk Factors for Feline Urinary Infection

UTI is seen more often in cats that are:

• Older than 10 years old
• Spayed female cats
• Abyssinian cats
• Overweight cats
• Diabetes Mellitus
  

Cat Urinary Tract Infection Symptoms

Cat urinary tract infection symptoms include:

• urine in the blood (haematuria)
• excessive, frequent urination (pollakiuria)
• slow and painful urination (stranguria)
• urination in places that your cat shouldn't (peniuria)
• blockage in the urethra
  

It is possible not to notice any symptoms of this condition. When symptoms do exist, often, like in people, there is a burning sensation caused by the bladder infection.  If you notice any sudden behavioral change when a cat is urinating,  its time to take your cat to the veterinarian for testing.

A similar condition is called FLUTD, FUS, Feline Urologic Syndrome and cystitis which is a feline lower urinary tract disease. This problem is caused by inflammation in the bladder that is not caused by infection. Symptoms can be similar to UTI because both are caused by inflammation in the same area of your cat's body.

Diagnosis of Feline Urinary Infection

Your veterinarian will take a urine culture for testing (urinalysis). The hard part is taking a urine sample that has not been contaminated by the environment or by your cat's lower urinary system. This can be done by either catching urine as your cat is urinating or by putting a non absorbent substance in your cat's liter box such as aquarium rocks or pellets. Your veterinarian may choose to insert a catheter into your cat which will provide the least contaminated sample.

Treatment of Feline Urinary Infection

Antibiotics are used to kill the bacteria which is causing the infection over a 10 to 14 day period.

85% of cats that receive treatment are cured of the UTI.

If your cat frequently gets bladder infections you might want to consider a natural remedy to support the bladder and urinary system. One product made for this purpose which is worth researching is PetAlive UTI-Free Formula for pet urinary tract infections. It contains natural ingredients such as Arctostaphylos uva ursi which helps maintain normal pH levels in the urinary tract. (Larsson B, Jonasson A, Fianu S. “Prophylactic effect of UVA-E in women with recurrent cystitis: a preliminary report.” Current Therapeutic Research 1993;53(4):441-443. ).

Helping to Maintain Cat Urinary Tract Health

The key to cat urinary tract health and feline urinary support is staying hydrated. The more hydrated your cat is, the more often he or she will urinate. Urination is the way nature cleans the bladder and prevents infection. It also helps to prevent stones, which can block the urinary system, from forming.

Cats naturally do not drink a large amount of water and get much of what they need through their diet. This is why many veterinarians such that cats that are slightly dehydrated switch to a "wet" or canned diet vs. dry kibble.

Bacteria can also enter your cat from a dirty litter box. Be sure to keep the box clean.
