Purring is often a sign of a happy and content cat, producing one of the most pleasant and soothing sounds for cat lovers. However, cats sometimes purr at unusual times, such as when they are sick, injured, or stressed. This behaviour, known as inappropriate purring, can indicate that your cat is experiencing discomfort or distress.
This guide will help you understand purring in cats, how to recognise inappropriate purring, identify possible causes, and what steps you can take to support your cat’s wellbeing.
Purring is produced by air flowing over the vocal folds in a cat’s larynx, causing vibrations on both inhalation and exhalation. Each cat has a unique purring sound, which varies in tone and intensity depending on the situation. Typically, cats purr to communicate pleasure, comfort, or to calm themselves down as they settle to sleep. The soothing sound benefits not only the purring cat but also others around them.
Inappropriate purring happens when a cat purrs during times of stress, pain, or illness rather than contentment. Cats use purring as a self-soothing mechanism to relieve anxiety and discomfort. This may also help mask loud external noises like fireworks, reducing their overall stress.
Interestingly, female cats often purr during labour to ease the birthing process and keep both themselves and their kittens calm.
It can be surprising for owners to hear their cat purring when the animal appears unwell or anxious. To determine if your cat's purring is appropriate:
If the purring accompanies symptoms like vomiting, diarrhoea, loss of appetite, or behavioural changes, it is important to take it seriously.
If you suspect your cat is purring due to stress or discomfort, consider the context and any other symptoms. Here are key steps to help your cat:
Cats are adept at concealing illness, so inappropriate purring can serve as an important early warning sign your cat needs help. Even if other symptoms are subtle or not yet visible, recognising stress or pain through purring allows you to act promptly and ensure your cat’s health and happiness.
Always promote responsible ownership by regularly monitoring your cat’s behaviour and health, seeking timely veterinary support, and providing a loving, stable environment.
