When it comes to pain, most cats would rather hide their hurt than appear vulnerable. So how can you tell when it’s time to intervene or let your sleeping cat lie?

Comfortable cats are curious in their environment but content at rest. As they become pained, their routine might change ever so slightly. With increasing pain, they become noticeably withdrawn and less responsive, often adopting a hunched stance and looking scruffy with dull eyes. As pain continues to ramp up, the same cats might actually vocalize more by crying, growling or hissing. Some will lick or chew at painful areas. Finally, severe pain causes many cats — even wild ones — to be completely listless and give in to handling without a fuss.

So be alert to a cat’s clues — because as discomfort increases, so does the need for pain relief.
