I can imagine taking a fall like that must have been quite distressing for both you, and I'm glad to hear that you didn't injure yourself. I hope it didn't take too long for your cat to forgive you for the wild ride. My two will hide up and sulk for a few hours just for having their flea and worming treatment put on the back of their necks. I shudder to think how long I'd be persona non grata if I had a similar mishap.
Admittedly, the last time I got an up close and personal encounter with the ground there was definitely a cat involved. I blame the meds for messing with my equilibrium, all I was doing was bending over to pick the cat up to bring her in for the night and the next thing I know, I'm flat on my face and feeling like a complete idiot.
