Rosy boa not eating
I've had my rosy boa since 2019, as a baby he was always a great eater, then once he was a few years old he stopped eating over winter, this year he stopped eating over winter as usual but it's July and he still hasn't eaten. I offer small adult mice once a week, I wave them in front of his face for a bit which used to always work, then I'll set them down in case he's shy and will eat while I've gone but this is never worked. I typically don't handle outside of cleaning.
Does he look healthy and is his setup ok? (it's where he's lived for years) How can I help tempt him to eat? When should I be worried and take him to a vet? Is prey size ok? He's pretty small
I should add he's always interested in the food, coming up to sniff it and rub his face against it but never any striking
