FUS in cats

It started relatively harmless: Persian Pasha showed the classic symptoms of cystitis. Often he pressed urinating and pressing small amounts of urine and found no peace even at night.

On the basis of a urine sample, the veterinarian diagnosed cystitis and urine semen. Against the inflammation antibiotics were prescribed and a special diet against the urine semolina. After a short time, there was an apparent improvement. But after a few days, the condition worsened acutely: tomcat Pasha sat only in the litter box, tried unsuccessfully to drop urine, and was no longer responsive to colicky pain. The veterinarian diagnosed a urethral obstruction. Pasha was anesthetized immediately. A catheter was placed and the bladder was rinsed with urine-dissolving drugs. The little cat was already suffering from urine poisoning.

bladder infection

If the cat frequently urinates and urinates in small quantities and shows pain, it may be a sign of incipient bladder infection or obstruction of the urinary flow through urinary stones or urine semolina. Both diseases can occur simultaneously and require immediate veterinary help. Other symptoms of cystitis include blood in the urine and cloudy (“cola”) urine, which often smells sharp. In the advanced stage, fever and disturbances in the general condition occur. When palpating the abdomen, the cat is sensitive to pain in the bladder area.

Effects on the kidneys

Cause of a bladder infection are often bacteria. The treatment can be very tedious and definitely belongs in the hands of the veterinarian. If this is not visited in time, the acute condition can lead to chronic cystitis and kidney effects, which are difficult to treat with medication.

urethral obstruction

Urethral obstruction (also commonly referred to as FUS = Feline’s Urological Syndrome) is the most feared condition among cat owners. Urinary stones or urine semen, which cause are in cats Indicator: Do your cat a treat often. Various statistical surveys show disease numbers between 06% to 1% of the cat population. The disease is not linked to age or gender, but hangovers and male castrates are most commonly diagnosed, as their urethra is longer than in females, has a smaller lumen, and has a lower elasticity. In diseased cats, bladder stones are always the cause of the disease, while in cats it can be both urine and urinary stones.

Mostly they are phosphate stones

There are different types of rocks whose composition can be determined by chemical analysis. About 90% of the cases are phosphate stones, a compound of ammonium and magnesium, also known as struvite. The reasons for the crystallization are not yet clear, but several factors seem to be involved in the formation of rocks. The most important cause is too high a concentration of urine. Cats generally drink less than their actual needs. As a result, the urine density (the specific weight of the urine) increases, the concentration of electrolytes (dissolved salts) in the urine increases. Another factor is the acidity of the urine, which is also feed-dependent. Struvite develops in an alkaline environment, so the urine must be kept acidic. Another factor can be the mineral concentration of the feed. Magnesium and phosphorus can cause the formation of stones. Furthermore, husbandry conditions can be an indirect cause. Dirty cat litter boxes are reluctant to use, and the cat indicator: make your cat happy holds back the urine, which in turn can affect stone formation. Urinary stones and semolina irritate the bladder mucosa.

The first signs are, as in cystitis, frequent and unsuccessful cat litter trays. If urine is discontinued, it is often bloody in the final jet. Some cats suffer from such severe urinary urgency that they try to urinate elsewhere as well outside the litter box. Sometimes the urge is so strong that the animal with feces unsuccessful squeezing. Tomcat licking constantly her penis, so that it suffers abrasions through the rough tongue. In some cases, small crystals can be seen on the penis tip. At the same time, gelatinous mucous plugs form in the urethra in response to the irritation and damage to bladder and urethral mucosa, which aggravate the constipation even further.

Life-threatening urinary barrier

The condition of urethral obstruction is life threatening. The bladder is getting fuller, but the urine can not be stopped anymore. The enlarged bladder is sensitive to the sensation and there is a risk that the bladder wall will rupture. Out of a large number of urinary substances (mainly end products of protein metabolism, such as urea or creatinine), which are otherwise excreted in the urine but now remain in the bloodstream, urine poisoning (uremia) develops within a few days, which further worsens the prognosis. A complete urinary barrier will max. Endure 48 hours, after that it is life threatening. The veterinarian anesthetizes the cat and introduces a catheter into the urethra. Urinary fluid-releasing medications are used to flush the bladder and urethra and at the same time prevent the formation of new blood. Sometimes the veterinarian can also massage out crystals and mucus plugs from the penis tip and thus solve the constipation. With the help of an ultrasound probe, which is introduced into the urethra, urine can be smashed. These measures can sometimes be used to avoid complicated surgery (penile amputation).

Prevent relapse

Since the recidivism rate is very high (about 50%), the formation of calculus must be prevented. The veterinarian can prescribe appropriate urinary diets that are available as wet or dry food. Display: Directly for sale on Amazon. In addition, there are various pastes and tablets that are supposed to acidify the urine and prevent struvite formation. The owner must pay attention to regular and daily urine sales. If the cat drinks too little, you can increase your thirst by adding salt to the wet food (1 g per 100 g of food).
