FLUTD stands for Feline Lower Urinary Tract Disease and is a term used to describe any group of disorders or diseases that affects the lower urinary tract (bladder or urethra) in cats. The most common disorder of the group is feline idiopathic cystitis (FIC). FIC involves inflammation by an unknown cause, but stress is thought to be a significant factor. FLUTD is also associated with the formation of crystals/stones in the urinary tract that can cause numerous and painful ailments for your cat. The two most common types of crystals/stones are struvite and calcium oxalate. FLUTD is serious and requires medical attention. Fortunately, you can help your cat recover with treatment from your veterinarian and the right nutrition.
Inappropriate urination is the number one behavior problem in cats. Many cats are given up to shelters for urinating outside of the litter box. If not properly treated, inappropriate urination can affect the cleanliness/safety of your home and the bond you share with your cat. The good news is that often, this problem is caused by a feline lower urinary tract disease (FLUTD) and it is a treatable medical condition.

FLUTD is a multifactor disease. There is no single cause of feline urinary tract disease. Veterinarians do recognize that there are components that may contribute to the prevalence of the disease. For more detailed information, always contact your veterinarian.
Risk factors include the following:
Nutritional Risks:
You already know that the food you feed your cat is extremely important to her overall health. But feeding the wrong food can contribute to the development of a urinary tract disease (FLUTD). With FLUTD, crystals or stones form within the urinary tract and cause irritation, pain and possibly blockage. In severe cases, this can lead to kidney damage or may even be fatal if not properly treated.
Home Environment Risks:
If your cat exhibits any of the warning signs of FLUTD, contact your veterinarian immediately. Especially if your cat is not urinating freely, a urinary blockage may be the cause and this condition may be life threatening. Consult your veterinarian immediately.
