Some cats will develop cystitis with no apparent underlying cause. These cats will usually have a normal urinalysis or a urinalysis that shows blood in the urine, but no crystals and no evidence of a bacterial infection. Urine culture is negative. Radiographs and ultrasound may show a thickened bladder wall but no crystals, no stones, and no evidence of tumors. These cats probably have feline interstitial cystitis, also known as sterile hemorrhagic cystitis. This condition is highly frustrating because there is no known treatment. These cats will usually exhibit signs on a cyclical basis. They usually show signs for three to ten days, then get better. Re-currence is common, but the frequency of episodes is highly variable from cat to cat and very difficult to predict. Owners always want to do something to help the cat, often insisting on antibiotic therapy. When the cat gets better after starting antibiotics, the owner assumes the antibiotics cleared up an undiagnosed infection. In reality, the syndrome simply ran its usual course of spontaneous remission. But many owners remain convinced that the antibiotics help and may spend unnecessary money on repeated courses over the years. Antibiotic therapy should be reserved for cats with a confirmed bacterial cystitis (diagnosed via urinalysis and/or culture of the urine) and for cats at high risk of developing bacterial cystitis as a result of urinary catheterization to relieve a urethral obstruction. Even then, antibiotics should be given when the catheter is removed, not when it is placed, to prevent encouraging resistent bacteria.
There is one therapy that may improve interstitial cystitis in cats. While not yet proven effective, early studies are encouraging. This therapy involves supplementing cats with a product containing glycosaminoglycans, an important component of the normal protective lining of the bladder. The theory is that cats with interstitial cystitis have a disrupted glycosaminoglycans layer in the bladder. Without this protective layer, the bladder wall is subject to damage done by contact with urine, which can be highly irritating. Cats receiving glycosaminoglycans supplements may suffer fewer, less severe episodes of cystitis. This supplement is available in a capsule that can be opened and sprinkled on the food. Most cats will eat this supplement when added to food.
Another therapy that has been tried is antiinflammatory doses of steriods. While we used to feel that this therapy helped some cats, we now realize that these cats probably would have gotten better on their own in about the same time frame. Recent studies suggest that steriods have no benefit in this condition.
We use Pneoxybenzamine n male kitties taht have been blocked and catherized. it may prove useful in your situation. It may not. Here is some additonal info on that drug:
