Is my cat's breathing sounding normal?

I've had my cat for around 3 months - she was a stray before that.shes very young (just one) and I took her to the vet who says she's healthy. I took her breathing rate - whilst at rest and relaxed she can be from around 26-30 which according to one website is quite high but when she's asleep it's usually in the 20s. Her regular breathing rate e.g when she's sitting upright is around 31 and can be higher depending on how relaxed she is/ what she's doing. I will ask the vet at the next check up - which is in around 4 months but I'm wondering if this needs a special visit or am I overreacting? One thing that worries me is that sometimes when lying down I can see her abdomen rise/fall very quickly for max. 2 seconds. My cat's always very alert and quite anxious as she's lived without a home so I'm wondering is that a part of that? Also on a website it says you shouldn't see your cat's belly move when she's breathing but when my cats curled up I can see her abdomen rise/fall (her chest is less noticeable to see) and when she lies on her back I can see her abdomen/belly rise and fall. My cats pretty skinny at the moment (I'm working on fattening her up) so what's your view on this?


I've attached the link for two videos of my cat breathing at rest:

It is probably nothing, but it is a bit high - 22 is the normal at rest rate. I would just monitor her over the next few months. There are one or two genetic conditions which can cause this, and I have personal experience of one, which is a hernia of the diaphragm. My Persil began to breathe fast around 4 months old, and then suddenly went off her food and just lay around all day. The vet treated her for gastro-enteritis, but it got worse and I thought she was dying, she was panting so much. Then a new vet did an Xray and found her diaphragm had ruptured completely and all her intestines had been sucked up into her chest. He was able to operate successfully and she is now 10 years old and leads a perfectly normal life. I don't want to frighten you ( I probably have) but I am only telling you because vets don't always think of this condition, and because if the diaphragm already has a hole, it tends to rupture as the kitten gets to a certain size. You could just mention it to the vet next time you see him and see what he says. At least she can be monitored.
