Maybe the vet can check your legs while you are there!!!!
Hope all goes well. Has he had his teeth trimmed before? Just curious really because I remember my tooth trimming trips with my gerbil and the poor wee guy, he got his teeth trimmed (he has one long, jagged lower tooth only) but it kept growing too fast and I remember having a horrible time trying to feed him soft food and his body condition deteriorating.
He had an injury to his teeth though rather than being old or requiring this to be done, otherwise it wouldn`t have been necessary. x
