Hi all, tomorrow I’m taking my female calico/tortie to get spayed . It’s a bit of a drive, 30-40 mins. Last time I took her out, she was open mouth breathing which I think is cat anxiety or something like that? Anyways, I really don’t wanna stress her out because I’m already dropping her off as is, any advice?

Edit: I’m not sure if the anxiety for my cat is related to the car, or her carrier. The one she used to use as a kitten is small so for tomorrow I’m gonna use a new one that she’s not used to.
