Increased thirst in cats can indicate a variety of things. It usually indicates a problem with the kidneys or the digestive system. Many owners are unconscious that their cats are drinking water or not. So, if you notice your cat spending more time by the water dish than usual, it could be a sign of something.
Urinary changes should always be examined. They frequently signal a urinary tract or kidney issue. Schedule a vet appointment if you detect a change in the frequency or quantity of urine, inappropriate urination, or blood in the urine. If your cat is trying to urinate and nothing comes out, this could be a medical emergency, especially in male cats, take your cat to the vet right away.
