I can so relate to this!! I have one - the naughty Bubba - who manages to put all fours out in such a way that it is impossible to get him in. I thought we were going to break his neck last time.

As for that awful yelling en route... and yet when I get to the vet they shut up and have to be coaxed out of the cage.

As you said, all for the good of them, but it's taxing on our emotions. Lovely story, Brendan!
