If a cat is unable to urinate, the first thing to do is check for urinary tract infections such as urethritis or cystitis. These conditions can cause symptoms like incomplete urination or inability to urinate. If the cat is also vomiting, it may be experiencing kidney failure and requires immediate emergency treatment at a veterinary hospital.

Before taking the cat to the vet, you can try catheterization, such as by bladder puncture or catheterization, to drain the urine and alleviate the emergency. At the same time, you can give the cat pet anti-inflammatory medication to relieve urethral edema.
However, these are only temporary measures. It is essential to take your cat to a veterinary hospital for a thorough examination as soon as possible to determine the cause and receive appropriate treatment. In daily life, attention should also be paid to ensuring a balanced diet for your cat to prevent the formation of stones and crystals, thus reducing the likelihood of such problems.
