The cat died suddenly and was still incontinent. It may be caused by the fact that it did not receive sufficient nutritional supply and was unable to supplement its body with nutrients. It may also be caused by a disease, parasites, etc., or by eating something by mistake.

It may be urethral obstruction, which is an acute urinary tract obstruction. Most common in male cats. Typical symptoms are straining to urinate and crying (due to pain). If left untreated, most cats will die within 72 hours. As long as you get vaccinated and dewormed regularly, pay attention to the environmental sanitation at home, put away dangerous items, and check your senior cats regularly, you can greatly reduce the chance of sudden death of your cat.
