It usually takes a week for a cat to regain its appetite after having a urinary catheter. The actual time depends on the cat’s condition. There is no standard answer. Most cats will regain their appetite after catheterization and when they feel comfortable. Some cats may have other problems caused by holding in urine for too long, and may not recover until the cat fully recovers.

Things to note after cat catheterization:

1. Put an Elizabethan ring on the cat, and do not let the cat bite off the catheter, or do not let the cat remove the catheter. Urinary catheter.

2. Observe the urine from the urinary catheter. If the cat is not given a urine bag after normal urination, the urine will drip directly from the urinary catheter. If there is no urine bag, you need to observe it at all times, because a drop of urine will drip out of the urine tube in 3-5 seconds, and urine will flow out continuously. At this time, you should pay attention to observe whether the cat has any of these symptoms. If so, it means that the urinary tract is not blocked. After cat catheterization, you should pay attention to the dripping of urine in the cat litter box. Be sure to pay attention to the litter particles in the cat litter box to avoid blocking the urinary tube.

3. If conditions permit, try to install a urine bag for the cat, because it is more convenient for the cat to install a urine bag. If the cat is not provided with a urine bag, the dripping urine will easily wet the skin and hair of the cat's hind limbs, leading to skin infection.

4. When catheterizing a cat, pay attention to monitoring the cat’s daily urine output, which will help determine its recovery from the disease.
