Vets prescribe painkillers to help your cat feel more comfortable after an injury, operation or a painful illness. The type of painkiller prescribed depends on the problem, as well as your cat’s age and general health. Human painkillers are not safe for cats.

Most cats will need painkillers (analgesics) at some point in their lives, especially as they get older. Sometimes treatment is for a short time, to help your pet recover from an injury or operation. Cats with arthritis may need painkillers every day to help them enjoy a happy active life. Side effects are common and depend on the medicine, but often include tummy upsets or sleepiness. Only use painkillers your vet prescribes.
