When I was at Laura's yesterday I met her daughter Bethany,who has recently moved back to Pboenix and is staying with Laura until her apartment is ready.  Bethany has a very friendly iguana (named Atreyu) that I got to meet.  When I started scratching Atreyu under her chin, she did exactly the same thing a dog or cat would do - closed her eyes and raised her head to give me better access.  

Here are some pix I took with my phone.

 

The colors/textures sure don't come through in the picture - but I love them!
