I have lost count also Lele, LOL lets just say ALOT !
All Pets, only sell offspring of the species I breed. 
I have to say I'm having a Blast, have learned so much and never wanna stop learning about them all. (you obviously know what I mean)
I find reptiles/ froggies fascinating, as well as ALL furry and feathery critters too. 
Like you, I'm lucky enough to also be at home during the day or I could not do it . Had my human kids right out of high school so they are both out and married with their own babies now.
**I'm in my later 40's and PLAYING with lizards NOW, LMAO 
Yeah, let me know if ya ever want a pretty collared, I breed some really colorful aquaflames, yellowheads, and other species of collareds as well. I never get tierd of looking at them they are so pretty !
Your question about the shield tail agama(oh isn't he the sweetest lil thing?)
anyway their tails in natural are used in a very interesting way, they go into their den , and block the enterance with their tails, like a door. LOL Its like a sheild to keep out predators.
I have been waiting patiently to purchase Chiumbo a little girl shield tail, and finally she will be ready in 2 weeks. I'm sure he will be DELIGHTED, even happier than me

Hey I'm super glad to be here with all you guys, everybody seems very friendly ( I LIKE that)
