My little corn seems to have taken to pooing on me. She hardly ever does it in her vivarium, I'm sure she waits until I've picked her up to, erm, let it all out. I know that this can be a defence mechanism, but I really don't think she gets stressed out by being handled. She usually poos when I've had her out for about 10 minutes and she has had a good old slither around. Are there any reasons other than stress that might make her do this?
