Did you know that 61% of cat owners fail to spot pain in their pets until it becomes severe? A landmark 2025 study by the Royal Veterinary College revealed that cats mask discomfort far better than dogs, making early detection crucial. In this article you’ll discover the five subtle behaviours that signal your cat is suffering—and the one sign that should send you to the vet immediately.
📊 Key Figures 2026

1. Excessive Grooming or Licking One Spot
When your cat obsessively licks or grooms one area of their body, it’s rarely vanity. This behaviour often signals pain, inflammation, or a hidden injury beneath the fur. Unlike dogs, cats won’t necessarily limp—they’ll focus on the problem spot instead.
Luna, a 6-year-old tabby from Manchester, was constantly licking her back leg. Her owner initially thought it was normal grooming until her vet discovered early arthritis. Early intervention meant Luna regained mobility within weeks.
✅ Expert Tip
Check for bald patches or raw skin during your daily petting sessions. If grooming is concentrated on joints (hips, shoulders, knees) or one limb, book a vet appointment within 48 hours—don’t wait for limping to develop.
2. Changes in Litter Box Habits
A cat that suddenly avoids the litter tray or struggles to squat is sending a distress signal. Pain in the lower back, hips, or abdomen makes the litter box feel like an obstacle course. You might notice them urinating outside the box or straining for longer than usual.
The British Veterinary Association (2024) notes that litter box avoidance is the second-most-missed pain indicator after behaviour changes. Many owners attribute it to stress or “acting out,” when it’s actually physical discomfort.
3. Reluctance to Jump or Climb
If your normally acrobatic cat suddenly avoids the cat tree, struggles to reach the sofa, or hesitates before jumping down, pain is likely the culprit. Cats won’t announce stiffness—they’ll simply stop doing what hurts. This is especially common in cats over 7 years old.
Watch for cats who take the stairs one step at a time instead of bounding, or who pause mid-jump. These hesitations reveal joint or spinal discomfort that’s easy to overlook if you’re not watching closely.
✅ Expert Tip
Document your cat’s movement patterns for 3 days: note jumping behaviour, stair use, and how they settle onto furniture. Share this video log with your vet—it’s far more revealing than a single clinic observation.
4. Withdrawn Behaviour and Loss of Appetite
Pain doesn’t just affect movement—it crushes personality. A cat that hides more, ignores you, or stops eating is experiencing significant discomfort. Chronic pain alters mood and appetite simultaneously because both are controlled by the nervous system.
The 2025 RVC study found that appetite loss combined with behavioural withdrawal was present in 73% of cats with moderate-to-severe pain. If your affectionate cat becomes a hermit or skips meals, don’t assume depression—suspect pain first.
5. Stiffness After Rest (Morning Lameness)
Watch your cat when they wake up or stretch after a long sleep. Difficulty standing, a wobbly gait, or reluctance to move immediately after rest strongly suggests joint pain or arthritis. This stiffness usually improves as the cat warms up, which is why many owners dismiss it.
Morning stiffness is one of the earliest signs of feline arthritis and is completely preventable with early intervention. Cats that stretch more cautiously or remain curled up longer than usual are telling you their joints hurt.
⚠️ Warning
If your cat shows sudden paralysis, inability to urinate, or severe distress, seek emergency vet care immediately. Combine three or more pain signs (grooming + litter avoidance + withdrawn behaviour) warrants a vet visit within 24 hours. Never give human pain relief—only prescription cat medication is safe.
Why Cats Hide Pain So Well
In the wild, showing weakness signals prey to predators. Your pet cat still carries this evolutionary instinct, which is why they’re masters of disguise when suffering. A cat’s pain threshold is also genuinely higher than humans’, so what feels severe to us might be moderate discomfort to them.
The PDSA (2024) emphasises that cats rely entirely on us to read their subtle signals. Unlike dogs who vocally complain, cats communicate through behaviour changes—and most owners simply aren’t trained to spot them.
What To Do If You Suspect Pain
Document the signs you’ve noticed over the past week: specific dates, times, and behaviours. Bring this record to your vet—it’s more helpful than trying to remember details during the appointment. Your vet will likely recommend blood work, X-rays, or other imaging to rule out serious conditions.
Early pain management can add years of comfort to your cat’s life. Whether it’s anti-inflammatory medication, physiotherapy, or lifestyle adjustments like softer bedding, catching pain early transforms outcomes dramatically.
The most surprising point many owners miss? Your cat’s pain might already be chronic. Cats don’t suddenly develop severe arthritis overnight—it builds silently over months. That’s why spotting early signs like morning stiffness or reluctant jumping is genuinely life-changing.
Have you noticed any of these behaviours in your cat recently? Don’t wait for obvious limping—book a check-up now if anything feels different. Your cat can’t tell you they hurt, but their behaviour can.
