Did you know that 68% of cat owners fail to recognise pain in their feline companions? Cats are masters of disguise when it comes to suffering—they evolved to hide weakness from predators, and that instinct remains hardwired today. A landmark 2025 study from the Royal Veterinary College (RVC) found that behaviour changes are the earliest and most reliable indicator of feline pain, yet most owners attribute them to normal ageing or mood swings. In this article you’ll discover the five subtle signs your cat is in pain that vets say are routinely overlooked—and how recognising them could prevent serious complications. The most eye-opening finding? A single change in your cat’s grooming habits might be telling you more than a thousand purrs ever could.
📊 Key Figures 2026
- 68% of cat owners miss early pain signals, according to RVC research (2025)
- Over 90% of cats aged 12+ experience chronic pain, yet only 23% receive pain management (PDSA, 2024–2025)
- Early intervention reduces recovery time by 40% in cats with musculoskeletal pain (International Journal of Feline Medicine, 2025)

1. Changes in Grooming Behaviour (The Most Missed Sign)
A cat that suddenly stops grooming or obsessively licks one area is sending a distress signal. Pain anywhere in the body disrupts the ritual of self-cleaning—cats prioritise survival over vanity when they hurt. If you notice matted fur, an unkempt coat, or bald patches from over-licking, your cat is likely experiencing localised or systemic pain.
Conversely, excessive grooming of a specific limb or body part can mean your cat is trying to soothe pain, much like you’d rub a bruise. This behaviour often precedes limping or obvious mobility issues by weeks.
✅ Expert Tip
Photograph your cat’s coat and behaviour weekly. Compare images month-to-month to spot gradual changes that might escape daily notice. Many owners only realise their cat has stopped grooming when a vet points it out.
2. Reluctance to Jump or Climb Stairs
Your cat suddenly prefers ground-level spots and avoids the cat tree or bedroom shelf? This is classic pain behaviour, especially in joints and spine. Arthritis, fractures, or abdominal pain all make jumping uncomfortable. Unlike dogs that limp visibly, cats simply refuse certain movements altogether.
Watch for hesitation before jumping or a stiff landing. Some cats crouch longer than usual before leaping, calculating whether the effort is worth the pain. Stairs become a major barrier—your cat may cry out softly or freeze mid-step.
3. Litter Box Avoidance or Straining
Pain during toileting is one of the most underreported warning signs. If your cat is visiting the litter box more frequently but producing less, or crying whilst eliminating, pain could be the culprit. Urinary tract infections, kidney disease, and gastrointestinal issues all cause this behaviour.
Some cats will eliminate outside the litter box entirely to avoid the pain association with that location. Others will strain visibly or spend unusually long periods in the box. This is never normal behaviour and demands immediate veterinary attention.
⚠️ Warning
If your cat hasn’t urinated in over 12 hours or is straining without producing urine, seek emergency vet care immediately. This can indicate a urinary blockage, a life-threatening emergency in male cats especially.
4. Unusual Vocalisation or Withdrawal
A normally vocal cat that becomes silent, or a quiet cat that suddenly cries out, signals pain. Cats communicate through meows, chirps, and trills—pain changes this vocal signature. Some cats cry when touched or moved; others simply stop interacting entirely.
Withdrawal from family members is equally telling. Your cat may hide in dark spaces for hours and show no interest in play, food, or cuddles. This isn’t sulking—it’s a pain response. A real-world example: Milo, a 7-year-old tabby from Manchester, hid behind the sofa for three days before his owner discovered a urinary blockage causing severe discomfort.
5. Changes in Appetite or Eating Patterns
Pain affects appetite and eating mechanics. If your cat eats smaller portions, avoids hard food, or chews only on one side of the mouth, dental pain or throat discomfort is likely. Cats with abdominal pain often approach the bowl but eat little.
Weight loss over 2–3 weeks coupled with reduced eating is a red flag. Some cats experience nausea alongside pain, making food unappealing. Monitor actual intake, not just bowl emptying—cats are skilled at pushing food around without eating much.
✅ Expert Tip
Weigh your cat monthly using home scales. Document the number. A loss of more than 10% body weight in under three months warrants a vet visit. This simple metric often reveals pain or illness before other symptoms appear.
The British Veterinary Association (BVA) emphasises that pain assessment requires a holistic approach: no single sign definitively confirms pain, but a cluster of behavioural changes almost always does. Trust your instinct—you know your cat better than anyone.
If you’ve noticed any of these signs, book a vet appointment. Early intervention not only reduces your cat’s suffering but can prevent secondary complications like muscle atrophy or psychological issues. Your cat can’t tell you in words that something hurts—but their behaviour is speaking volumes. Have you noticed any subtle changes in your cat’s routine that you’ve been meaning to investigate?
