Cats have a way of stealing hearts with their soft purrs and playful curiosity. But just like any loved one, they sometimes face health challenges that can leave us worried and unsure of what to do. Whether it’s a sudden change in behavior, a loss of appetite, or an unexplained sneeze, knowing how to spot the signs early can make all the difference. This guide will walk you through the most common health problems in cats, how to recognize them, and what steps you can take to keep your furry friend safe, comfortable, and healthy.

Important: If your cat has labored breathing, collapse, seizures, or is straining to urinate with little or no output, seek emergency care immediately.

1.General warning signs

  • Hiding, reduced appetite, or drop in activity
  • Weight loss or sudden weight gain
  • Vomiting more than once a week, or diarrhea
  • Coughing, wheezing, or noisy breathing
  • Changes in thirst/urination, or accidents outside the box

2.Digestive issues

Vomiting & diarrhea

Causes range from dietary indiscretion to infections or systemic disease. Persistent symptoms, blood, or lethargy warrant a vet visit.

Hairballs

Frequent hairballs can signal overgrooming, diet issues, or GI problems. See Grooming for Long-Haired Cats and How to Read Cat Food Labels for grooming and diet tips.

3.Urinary problems

Straining, frequent trips, or blood can indicate infection, stones, or feline lower urinary tract disease. Male cats can obstruct

4.Dental disease




Bad breath, drooling, and pawing at the mouth suggest dental pain. Routine dental checks and gentle home care help. See Signs of a Healthy Cat (mouth & teeth basics)

5.Parasites

Fleas, ticks, mites, and internal parasites (roundworms, tapeworms) can cause itch, anemia, or GI signs. Use cat‑safe preventives; keep litter boxes clean and scooped daily.

6.Upper respiratory infections

Sneezing, eye/nose discharge, and mild fever are common. Isolate from other cats, keep the nose/eyes clean, run a humidifier, and seek vet care if appetite drops or breathing worsens.

7.Obesity & diabetes risk

Portion control and appropriate calorie targets are key. See How to Read Cat Food Labels

8.Senior cat red flags

  • Increased thirst/urination (possible kidney or endocrine disease)
  • Night yowling, disorientation, or altered sleep
  • Stiffness, difficulty jumping, or matted coat from reduced grooming

9.When to see a vet (quick guide)

NOW / ER — go immediately

  • Known/suspected poison (lilies, string/thread, chemicals), or swallowed string

Within 24–48 hours:
