Is My Cat in Pain?

One of the most common questions I hear from clients is, “Is my cat in pain?”  Sometimes, the answer is an obvious “yes,” but occasionally it is more difficult to tell. Cats are very good at hiding signs of pain — an instinct picked up from the wild where the sick and the weak don’t survive long.  

As a general rule, we can assume that a limping cat or a cat with a cut or a tumor is in pain. Pain also commonly results from bad teeth, a bite wound, diseases (like pancreatitis or arthritis) or any type of surgery.

Cat pain is very subjective and notoriously difficult to assess.Cat laying down Signs depend on the individual, the breed, and the age. For example, we frequently see patients with bone fractures. You might think that all of these patients come in with obvious pain: moaning, panicking and biting. Some do, however, others simply purr! It’s a common misconception that a purring cat is happy or comfortable one.

What are common symptoms of cat pain?
Pain may be represented by:

  • An unusual posture (hunched back, sitting, resting or laying abnormally)
  • The head or tail hanging down
  • Abnormal movements (lameness, stiffness or thrashing)
  • Vigorous attempts to escape
  • Aggression
  • Hyperventilation (rapid, shallow breathing)
  • Hiding in unusual places
  • Vocalization (crying, hissing)
  • Inappropriate or difficult urination or defecation
  • Difficulty getting up (often mistakenly attributed to arthritis)
  • Difficulty grooming
  • Lack of appetite
  • Licking a wound or a surgical incision

Arthritis in cats
Arthritis deserves a special mention, because cats respond to it differently than dogs. Dogs typically limp, whereas cats rarely do. Instead, the most common sign of cats with arthritis is a reluctance or inability to jump up or down.
Other signs include:

  • Personality changes
  • Sleeping more
  • Hiding
  • Stiffness
  • Decreased grooming
  • Muscle loss in the affected leg

Good and bad pain medications
No matter how much pain you think your cat is in, never give him human drugs (or “doggie” drugs that have not been prescribed by your veterinarian). Not only can they be seriously harmful or deadly (e.g. aspirin, Tylenol® and other anti-inflammatory drugs), they can prevent your vet from using a whole category of other drugs. Veterinarians now have several pain medications
