For cats who have developed the habit of using litter boxes to urinate suddenly, we should consider the following common factors. One is pathological reasons: such as urinary tract crystallization and stones; Urinary tract problems with no known cause). The second is behavioral reasons: for example, there is a specific preference for cat litter box or cat litter; or urine spraying behavior caused by estrus. Generally, the priority of pathological factors is higher than that of behavior, that is, when the cat has unacceptable urination behavior, pathological factors should be considered first.

The urethra of cats, especially male cats, is thinner and narrower than that of other animals, so the probability of urinary system diseases in cats is relatively high. Feline lower urinary tract syndrome has been widely used to describe a disorder of the posterior urinary tract in cats. Although a specific etiology cannot be identified, associated etiologies include urinary tract infection, neoplasm, trauma, urethral obstruction, urolithiasis, and sterile cystitis. In terms of the probability of occurrence, the proportion of cystitis caused by bacterial infection is actually not high, so not all cats with urinary tract problems need to use antibiotics!

In the usual feeding process, the main cause of urinary tract diseases is related to the feeding method.
Unbalanced proportion of mineral content in food
· Drink less water
· Obesity and lack of exercise
The potential cause of cat litter, causing cats to lick their vulva frequently and cause inflammation
·anxiety
Symptoms a cat may experience:
·Frequent urination: Increase the number of times you go to the litter box, and the urine output will decrease, or if you squat for a long time without seeing half a drop of urine, you will find that the urine clots in the litter box are obviously smaller and more in number .
Hematuria: If you are lucky, you may find bright red urine sticking to the outlet of the cat's foreskin
Frequent licking of the genitals: Inflammation may cause pain and burning sensation in the urethra, cats will lick to relieve discomfort.
Painful urination: The cat will rush to the litter box in a hurry, and will howl in pain while urinating.

Disorderly urination: In the state of inflammation, it will cause dysfunction of the urethral sphincter, making it impossible for the cat to reach the litter box to urinate in time, or to urinate in a place other than the litter box unconsciously.
Vomiting: When the urethra is blocked, the urine cannot be discharged smoothly, and many toxins in the body cannot be discharged through the urine, so they accumulate in the blood circulation and cause vomiting, which is the so-called uremia. If it cannot be treated in time , the cat fell into a coma due to acute uremia 48-72 hours later, and eventually died.

Two treatments:
85% of cases of idiopathic cystitis resolve within 2-3 days even without treatment, especially in female cats
Pain management is very important, but the types of "painkillers" available to cats are very limited, and most of the drugs used by humans can cause poisoning, so it is best to consult a professional veterinarian before using them
Not all frequent urination, urinary anuria, and hematuria require antibiotics, and the abuse of antibiotics should be avoided to lead to drug resistance
·As long as you can still urinate, you don’t need a catheterization
·If it is not a last resort, urethrostomy surgery is not recommended, and postoperative complications should also be taken into consideration

Prevention: 1. Pay attention to the daily urination of cats to prevent problems before they happen
2. Use high-quality cat litter to prevent ascending infection
3. Choose high-quality cat food and feed pure water, which can appropriately increase the proportion of wet food and the fun of drinking water, so that cats can drink more water
4. Do not try to change the pH value of cat urine to reduce the occurrence of stones by changing the acidity and alkalinity of food (it is another matter if you have already suffered from urolithiasis)
5. Promote cats to exercise more with various toys such as cat teasers
6. Sterilization or not has no difference in the incidence of lower urinary tract syndrome, but attention should be paid to avoid obesity, because if you are fat, you will not like to move, and if you don’t like to move, you will drink less water, and the crystals in the urine will be easily oversaturated
6. Do not change the familiar living environment of the cat at will to avoid anxiety!
