What is FUS ? FUS – Feline Urological Syndrome also known as Crystals which accumulate fine crystals within the bladder and urethra.

Signs Your Cat May Have FUS – Feline Urological Syndrome

Straining, discomfort, sometimes bleeding into the urine, and, in male cats, possibly complete obstruction of the urethra so that the cat is unable to urinate. This is only likely to occur in males because in females the urethra is much wider and the debris can be passed.

Causes

It is not fully known exactly why some cats develop FUS, but it is clear that diet plays a major part. The crystals that form are usually based upon a substance called struvite, which is a crystalline compound of magnesium that tends to form in an alkaline urine.

Treatment

A diet that is low in magnesium and produces an acidic urine can play a major role in treating and preventing recurrence in susceptible cats, but it is not known why one cat develops the problem on a normal complete feline diet whereas another may not. But after treatment reevaluate and find a better brand of cat food that will not cause this. As though it’s known that lower no name and some commercial brands help contribute to this problem even though it might say it helps the urinary track. They can stick that on the label even if it helps 0.001% only. So why take a chance. Get a better quality food and help to avoid this problem.

Surveys have shown that the problem is more common in cats that are neutered, overweight, and not very active although of course these factors could be well be linked to each other It is vital that the owner of a male cat realizes that if their cat is straining to urinate and in obvious distress, it could be suffering from a urinary blockage and needs immediate vet attention to avoid serious damage to the bladder and kidneys as well as death.

Cats with blockage obviously need to have it cleared and to have a urinary catheter to put into place under anaesthetic if it has progressed into a dangerous level. If the obstruction cannot be cleared, or the urethra keeps blocking up again when the catheter is removed, a permanent by-pass operation, called a perineal urethrotomy, may be performed. This piece of plastic surgery reshapes the lower part of the male urethra to resemble that of the female.

Medical treatment of FUS mainly involves a change of diet to a complete pre-repaired food that is low in magnesium and produces an acidic urine. The brand that the vet will recommend is the brand they carry that is a bit expensive but if food is something that will help your cat, you are saving more then you know. For the catheter to the more intense surgery in Canadian dollars you are looking at around $300- 500.00 depending on vet. So buying the canned cat food for about $30.00 for a slab of 24 cans are a darn good option. Usually the crystals will be eliminated within a month or two depending on the case.

Antibiotics are often given to prevent secondary infection, and although bacteria cannot usually be cultured from the urine, antibiotics often seem to help alleviate the discomfort.

Cats that suffer from the repeated bouts of lower urinary problems are usually X-rayed to rule out other problems, such as large calculi (stones) that may form within the bladder, and tumors of the bladder wall, which are sometimes seen in older cats.
