I had been dreading the idea of taking Althea (this one https://www.instagram.com/p/BJsfQqIj0Hm/) to the vet, since she had bad vet experiences before we adopted her and for many years was unwilling to be handled. but she was so good and brave today! I had no trouble getting her into her carrier, she only yowled once on the bus (when I was out of her sight for a second), and let the vet examine her with no problems. (just a routine checkup, she's apparently quite healthy!)
during the trip she kept on exchanging meaningful glances with me, which I prefer to interpret as "I know you are making me do this unpleasant thing only because it is your necessary responsibility" and spent the bus ride there aggressively nuzzling my hand through the mesh of the carrier. but on the way home she was perky and alert and looking at the world around her from inside the carrier, almost like she was enjoying herself! (she's an indoors-only cat normally)
@aparrish as you should be
