Running up five stairs of flight is bound to make you pant and heave like your lungs are not getting enough air, but if cats or newborn kittens do it, it may be serious.

Cats are not ever known to be breathing from their mouths or panting but it’s not rare.

Rigorous playing or working themselves may cause them to breathe heavily or pant. This phenomenon is also seen to be happening with newborn kittens.

When a kitten is born they hiss or try to hiss, which is oddly familiar to the action of panting, so if you feel like your kitten is panting look closely to see if it is actually panting or just hissing. It may be a false alarm and closer inspection might save you a panicked phone call or a visit to your vet.

Recently I came across a cat owner on social media who shared the story of how she had to urgently take in a pregnant cat for a friend.

The cat gave birth to 6 kittens, who were checked by the vet and were healthy, but she noticed that of the kittens was breathing heavily and it seemed like she was trying to take in a lot of air but just couldn’t do it, so she rushed to the vet in the middle of the night to get her checked but turns out the little baby cat was just trying to hiss and couldn’t do it.

So you need to yourself check carefully and make sure if they are actually unconventionally breathing or you may be reading the signs wrong.
