Ever caught your cat breathing with its mouth open and wondered, “Why do cats pant?” It’s not something you see every day, and it can feel alarming when you do. After all, cats aren’t like dogs, who huff and puff happily after a walk or play session.
When a cat starts panting, it’s usually a sign to pause, observe, and sometimes even take action. Let’s explore why cats pant when it’s normal and when it’s time to call the vet.
Is It Normal for a Cat to Pant?
Unlike dogs, cats don’t usually pant as part of their everyday behaviour. So when it happens, it grabs your attention — for good reason. While it can be harmless in certain situations (like after a wild game of zoomies), open-mouth breathing in cats is often a sign that something else is happening.
Normal breathing for a relaxed cat is calm and quiet, with about 15–30 breaths per minute. If your cat is breathing heavily, especially with their mouth open, it’s time to look closer.
1. Playtime and Physical Activity
One of the most common reasons cats pant is simple: they just had a blast.
Some cats may pant briefly to catch their breath after chasing feather toys, sprinting down the hallway, or climbing their cat tree like a jungle gym. This is especially true for young, energetic cats or certain breeds like Bengals or Abyssinians.
What to do: Give your cat a chance to rest and offer water. If the panting stops after a minute or two, it’s probably nothing to worry about.
2. Overheating
Why do cats pant when it’s warm? Like us, cats can overheat—especially during hot, humid days or after intense activity. While cats cool themselves by grooming and sweating slightly through their paws, sometimes this is not enough.
If your cat is panting, lying flat on a cool surface, and seems sluggish, they may be trying to cool down.
Warning signs of overheating or heatstroke:
- Lethargy
- Drooling
- Rapid breathing or panting
- Red or pale gums
- Vomiting or staggering
What to do: Move them to a cool, quiet place and offer fresh water. If symptoms continue, call your vet immediately.
3. Stress or Anxiety
Visiting the vet, new people in the house, loud noises — even a car ride — can all stress your cat out. And one of the lesser-known symptoms of feline anxiety is panting.
Why do cats pant when they’re scared or nervous? Their body enters “fight or flight” mode, which triggers rapid breathing and sometimes open-mouth panting.
What to do: Create a calm space for your cat to retreat. Use familiar blankets, soft music, or calming pheromone sprays. If possible, try to reduce the trigger.
4. Pain or Discomfort
Cats are masters at hiding pain. But if they’re hurting, you might notice small changes in their behaviour — including panting.
Pain-related panting can stem from an injury, internal issue, or post-surgery discomfort. If your cat is hiding, limping, vocalizing more, or just “not themselves,” it may be time for a check-up.
What to do: Contact your vet, especially if other signs, such as restlessness, appetite changes, or sensitivity to touch, accompany the panting.
5. Underlying Medical Conditions
If you’re still wondering, “Why do cats pant when they haven’t even moved much?” There could be a medical reason behind it.
Some possible conditions include:
- Heart disease
- Respiratory infections
- Asthma
- Heartworms
- Anemia
Any of these issues can interfere with your cat’s ability to get enough oxygen — causing them to breathe faster or open their mouth to compensate.
What to do: Don’t wait. Unexplained or frequent panting is a reason to book a vet appointment ASAP. Early detection is everything.
When Should You Be Concerned?
Occasional panting during play or on a warm day isn’t always a red flag. But if your cat is panting:
- Regularly, without a clear cause
- For more than a few minutes
- Alongside other symptoms (vomiting, drooling, hiding, restlessness)
- While at rest or sleeping
It’s time to see your vet. Better safe than sorry.
