Warning Signs to Watch

Cats rarely show obvious pain. These subtle signs often indicate something needs attention. When in doubt, contact your vet. If your cat is sneezing or has a runny nose, see can cats get colds for causes and when to worry.

  • Eating noticeably less or refusing food for more than 24 hours
  • Vomiting more than once or twice per week
  • Changes in litter box frequency or straining to urinate
  • Excessive hiding or sudden aggression - sometimes confused with autism-like behaviors in cats
  • Labored breathing or open-mouth breathing at rest
  • Weight loss over several weeks without dietary changes

Prevention Basics

Simple habits that protect your cat's long-term health.

Annual vet visits

Even healthy-looking cats benefit from yearly checkups. Bloodwork and a physical exam catch issues long before symptoms appear.

Keep vaccinations current

Indoor cats still need core vaccines. Diseases can enter through open windows, shoes, or contact with other animals during vet visits.

Monitor body weight

Weigh your cat monthly. A consistent scale reading is one of the best early indicators of health changes in either direction.

Dental hygiene

If brushing is not realistic, dental treats and water additives help. Ask your vet for options that work for your cat's temperament.
