Feline Cystitis and Bladder/Kidney Stones - Feline Nutrition

Diet can have a profound effect on bladder health. Having evolved on the African savannah, felines have a low thirst drive. Prey animals contain about 70% water. By contrast, dry kibble has only 10% water, so cats that eat only kibble will have more concentrated urine and a higher tendency to form crystals. Feeding more canned food and even watering it down a bit increases liquid intake. Raw food diets also provide more dietary liquid.

If your feline friend is suffering from bladder stones, he may exhibit the following signs:

Feline cystitis, sometimes called feline cystitis or FIC, is an inflammation of the bladder that causes symptoms of lower urinary tract disease. However, in the case of , a definitive cause for the disease cannot be identified.


Have a story to tell about feline bladder stones or want to ask aquestion of our readership? A common condition in cats, lower urinary tract disease is often nonobstructive in nature. In fact, according to a 1997 study 45% to 70% of feline lower urinary tract disease is diagnosed as idiopathic cystitis. The clinical signs associated with idiopathic cystitis (dysuria; stanguria; hematuria; pollakiuria; and periuria, or inappropriate urination) are thought to be due to various anomalies in the bladder, central nervous system, and hypothalamic-pituitary-adrenocortical axis. Changing a cat’s environment, reducing stress, and increasing water consumption are some proposed ways to lessen the clinical signs of idiopathic cystitis.

Feline Bladder Cancer - Feline Instincts

Sometimes cats who have had bladder infections develop anxiety relating to urination and stop using the litterbox. Your veterinarian will want to make sure the infection is under control, but if she determines that anxiety is the cat’s problem, anti-anxiety medications such as fluoxetine (Prozac®), clomipramine (Clomicalm®) or amitriptyline (Elavil®) may be used. Another option is a feline stress-relieving pheromone (®), available as a , , or .

MB MRCVS from Pet Synergy in relation to Feline Bladder Cancer

The oval structures seen in the urinary sediment were identified as Capillaria sp. eggs. Nematodes of the genus Capillaria comprise a very wide group of parasites found in all classes of vertebrates (). The adult worms are typically attached to epithelial surfaces and, in dogs and cats, they have been associated with the intestinal and urinary tract, as well as the bronchi (). Capillaria plica and C. feliscati are parasites rarely found in the bladder of dogs and cats, respectively (). They are widely distributed and can be found in numerous domestic and wild carnivores (,). Adult C. plica are embedded in the bladder epithelium and, occasionally, within the ureter or the renal pelvis, where they can cause mild inflammatory reaction and submucosal edema (). Capillaria feliscati are essentially free on the surface of the bladder mucosa (). Adult bladder worms are small threadlike parasites. Adult females measure 30 to 60 mm, males 13 to 30 mm long (). Eggs are oval and colorless with a thick capsule and typical bipolar plugs (). Their sizes range from 22 to 32 μm in width by 50 to 68 μm in length ().
