affectionate reptile

I'd say leopard geckos show slight affection. I had one that was pretty neat.

Oh also now that I have more time ill go into more details as to why beardies are dog like imo. They have very different personalities, and their moods change from day to day. You can teach them things and its funny when they do stuff on food day. Leela my girl beardie knows what time food comes, so the second I open her cage ( Sliding glass doors) and jumps from her perch and RUNs to the edge of her cage, its sorta funny when people watch for the first time because they think shes running to jump out. My other beardie Fry tells me when he gets hungry, he sits perfectly flat on his food bowl and stares me down. If someone else was holding my old beardie Nugget he would try to get on me instead :p And other times my old beardie Nubb Nubb would glass dance every time I came into the room, and not again after I held him and put him back in.

Its small stuff but it sure is awesome:)
