You can breed a pair if you place them together.

Cage Size – the minimum size of a cage for an adult is 30” L x 12” D x 12” H.

For  substrate use  cage carpet, sand or powdered walnut shell.  The main anxiety of having sand and walnut shell is its chance of impaction. Overdose of substrate consumption leads to blockage in the intestines.  This you can avoid  by laying a cage carpet, which of course is not easy to clean.

On the cooler portion of the cage provide  a dark spot for hiding

Provide an open area for the spiny lizards to play around.

For climbing facilities, place vines, sticks and logs everywhere in the cage.

Provide a high level location for basking

Their hobby lies in digging into decayed logs.


Feed them with ½ or smaller portion of the cricket’s head around 5 pieces a day, and dusted with vitamin D3, calcium supplement twice a week. Once in a way give them a treat of grasshoppers, worms and beetles’.

Do not feed your juveniles with meal worms.  It is hard for them to digest exoskeleton. You would do well not to  feed meal worms to the adults. As food, they like butterflies most. They take pleasure, jumping about in the air.


Texas spiny lizards are the right selection for a small pet. These pets, without hesitation, eat crickets that you can easily buy commercially, they adjust well as captives and they are sturdy.
