Cats are experts at pretending everything’s fine. 🐾 It’s one of their greatest survival instincts — and one of the biggest challenges for cat parents. By the time a cat shows obvious signs of pain, the problem may already be serious.
As a certified veterinary technician with over 20 years of experience, I’ve helped countless cat owners learn how to spot the subtle clues that something isn’t right.
Here are five common signs your cat might be in pain, plus how to know when it’s time to call your vet.
🐾 Changes in Behavior or Personality
If your usually affectionate cat suddenly hides, avoids attention, or becomes irritable, it may be their way of saying something hurts.
Cats in pain often withdraw from family life, hide under furniture, or stop greeting you at the door. Some even growl or hiss when touched.
💡 Vet Tech Tip:
Behavior changes are one of the first and most important clues. If your cat’s acting “off” — especially if it lasts more than a day or two — don’t assume they’re just moody. Pain or illness could be the cause.
🐈 Changes in Grooming Habits
A healthy cat spends hours each day grooming. If you notice your cat grooming less — or not at all — it could mean they’re uncomfortable or stiff. On the other hand, over-grooming one area can also signal pain, especially if the skin looks red or thin.
💡 Vet Tech Tip:
Over-grooming around the joints often points to arthritis pain, while excessive licking on the belly or sides may indicate discomfort in internal organs. Watch for bald patches or irritated skin.
🩺 Changes in Appetite or Drinking
If your cat stops eating, drinks excessively, or avoids food altogether, that’s a red flag. Pain in the mouth, teeth, or internal organs can make eating uncomfortable.
💡 Vet Tech Tip:
Even skipping one meal can be dangerous for cats, especially overweight ones — it can lead to a serious condition called hepatic lipidosis (fatty liver disease).
If your cat refuses food or water for 24 hours or more, call your vet immediately.
🐾 Changes in Movement or Posture
Is your cat suddenly hesitating to jump, climb, or use the stairs? Do they walk stiffly or limp after resting? Cats in pain often change how they move.
You might also notice them sleeping curled tightly, hunched over, or keeping their head lower than usual — these can be signs of discomfort.
💡 Vet Tech Tip:
Arthritis is more common in cats than most people realize, even in younger ones. If your cat’s movement changes, don’t dismiss it as “getting older.” A vet visit can make a world of difference.
🐕🦺 Changes in Litter Box Habits
Painful cats often associate the litter box with discomfort — especially if they have arthritis, urinary issues, or constipation. They may start going just outside the box, using another surface, or straining to urinate or defecate.
💡 Vet Tech Tip:
Any straining in the litter box — especially if no urine comes out — is an emergency. Male cats can develop life-threatening urinary blockages that require immediate vet care.
🐾 When to Call the Vet
It’s time to call your veterinarian if your cat:
- Hides for more than a day or two
- Refuses food or water
- Shows sudden aggression or fear of touch
- Has difficulty jumping or walking
- Strains or cries in the litter box
If your gut says something’s wrong — trust it. Cats rarely “act sick” unless they truly are.
🐱 Final Thoughts
Cats are subtle creatures, and their way of showing pain is easy to miss. But once you know what to watch for, you can catch issues early and help your feline friend stay comfortable and healthy.
When in doubt, call your vet — it’s always better to check than to wait and worry. Your cat’s health and happiness are worth it. 💙🐾
