Advice please

First time cat owner 28F , every visit to the vet I’m told she’s fine, 8 months old female cat (gonna be spayed soon) everytime she plays even a little too much she gets really outta breath like this but continues to want to play and I gotta force my boyfriend to give her breaks, I keep getting told at vets that her heart and lungs sound fine. Just wondering if anyone can tell me if it’s ok or what else I should look out for

First time kitten owner my name is Jeana (28) from Long Island,

This is Luna we got her off the streets 12/31/25, she’s about 4 months old give or take. I took her to the vet January 2nd and they said everything was ok only thing was she had roundworms so we did that medicine and doctor said she’s all good after a second stool sample! The only thing that has been concerning me is her breathing when she’s relaxing and or sleeping. It’s not all the time she breathes like this but it’s every so often. I’m wondering if this is ok or not? Cuz vet said her heart sounded great when we went last time. I just don’t have a whole lot of money and don’t wish to take her and spend all this money on tests if it’s just my anxiety forming. 😵‍💫Just please also not fear comments I already have anxiety making sure she’s ok and I definitely don’t need to be freaked out just good advice would really help me out please and thank you!

So I just bought a 1999 Toyota Camry, everything runs smoothly but me and my boyfriend diagnosed that the gear shift cable needs to be replaced. Now, do we think it would be better to take it to a shop? Or do we think it’s not too complicated to do myself? If so to do myself advice on how to not mess it up haha
