Why is pain in cats so hard to spot?
Cats are evolutionarily wired to hide weakness. In the wild, visible suffering signals weakness, and prey status. As a result, many cats present a remarkably "normal" picture even when in significant pain. Owners often notice only late that something is wrong.
Typical pain indicators in cats are strongly behavioural: a cat no longer jumps onto the couch or counter. She suddenly grooms less, or excessively in one spot. She sits in the classic "meatloaf" position with a tense belly. She eliminates outside the litter box because stepping into it hurts. She hides in unusual places.
How the BEAP Pain Score for Cats works
The BEAP Pain Score (Behavior Evaluation And Pain) was developed by BluePearl Pet Hospice, a US veterinary group specialising in hospice and palliative care. The cat version captures pain across eight cat-specific observation fields:
- B — Breathing: calm vs. increased rate, possibly open-mouth breathing
- E — Eyes: bright and alert vs. partially/fully closed, dilated pupils, panicked look
- A — Jumping / movement: agile vs. avoids jumps, won't get up at all
- A — Activity: play, grooming, hiding, litter-box "accidents"
- A — Appetite: normal appetite vs. finicky, loss
- A — Attitude: playful vs. withdrawn, growling/hissing, aggressive
- P — Posture: relaxed vs. "meatloaf" position, fluffed fur, "grimace face"
- P — Palpation: relaxed vs. pulling away, growling, hissing, rigid body tension
For each category you select the level that best describes your cat, from 0 (no pain) through 1–2 (mild), 3–4 (moderate), 5–6 (moderate to severe), 7–8 (severe) to 9–10 (worst pain possible).
What does the result mean?
- 0 — No pain: No visible signs. Mention it at the next routine visit.
- 1–2 — Mild pain: Discuss at the next visit with your vet.
- 3–4 — Moderate pain: Book an appointment for assessment.
- 5–6 — Moderate to severe pain: Concerning. Please see your vet promptly.
- 7–8 — Severe pain: Very concerning. Please see your vet urgently.
- 9–10 — Worst pain possible: Emergency. Contact the practice or emergency service immediately.
How to observe a cat well
- Observe your cat in her familiar environment — at the vet, many cats hide pain even more.
- Compare current behaviour with your cat's usual behaviour — the scale rates change from baseline.
- Watch for hidden clues: avoiding the litter box, fewer jumps, less or excessive grooming, hiding in unusual places.
- Document over several days — with chronic pain (e.g. osteoarthritis in older cats) the trajectory matters.
- Note specific findings: time of day, which movement, which body region — this helps us a lot in consultation.
