I have a python named Sid. A beautiful and surprisingly affectionate critter. Low maintenance and a great conversation starter ... "my kids came back from school with it one day, they were all like: it followed us home Dad can we keep it!?"
I really want to know what this one trick was.
He has learned that when I come near the terrarium, I'll open it, so when he wants to come out, he will come up to the screen and look for the opening. I did not expect a tiny reptilian brain to be capable of learned behavior, it was a nice surprise.
