Most of us Texans used to catch and play with our horned lizards as children. They are harmless, never try to bite and so cute. If you turn them on their backs and rub their little tummys, they'll go to sleep.
They used to be EVERYWHERE- along roads, fields, in your yard. Now it is almost impossible to find one due to man's encroachment upon their habitats and those d*mn fire ants.
I love horned lizards. I remember catching them in the CA desert and even sometimes in the foothills. One we had and kept in a terrarium actually laid dozens of leathery little eggs. They are so cute.
