Common Cat Health Issues to Watch For
Published on September 25, 2025
Cats are masters at hiding illness, a survival instinct inherited from their wild ancestors. As a cat owner, learning to spot subtle changes in their behavior is one of the best things you can do for their health. Here are a few common issues to be aware of.

Dental Disease
One of the most common health problems in cats, dental disease can be painful and lead to more serious issues if left untreated. Look for bad breath, drooling, difficulty eating, or pawing at the mouth. Regular vet check-ups are key to catching dental problems early.
Urinary Tract Issues
Feline lower urinary tract diseases (FLUTD) can be very serious, especially in male cats. Signs include straining to urinate, frequent trips to the litter box with little output, urinating outside the box, or crying out in pain. If you notice these signs, especially straining, it is a medical emergency that requires immediate veterinary attention.
Fleas and Other Parasites
Even indoor cats can get fleas. Excessive scratching, hair loss, or seeing small black specks ("flea dirt") on their fur are common signs. Intestinal worms are also common, especially in kittens. Year-round flea prevention and regular deworming as recommended by your vet are your best defenses.
General Signs of Illness
Beyond specific conditions, it's important to know the general signs that your cat may not be feeling well. Your observations are critical to helping your vet diagnose a problem.
- Changes in Appetite or Thirst: A sudden increase or decrease in eating or drinking can signal a problem.
- Hiding or Lethargy: A cat who is suddenly hiding more than usual or has low energy may be in pain or not feeling well.
- Vomiting or Diarrhea: While an occasional hairball is normal, persistent vomiting or diarrhea is not.
- Changes in Grooming: A messy, unkempt coat can be a sign that a cat doesn't feel well enough to groom itself.
Knowing your cat's normal routine and behavior is the best tool you have. If something seems "off," it probably is. Trust your instincts and don't hesitate to call your veterinarian.
