Vegetarian desert lizards that need serious heat — and reward it with decades of pet-rock charm.

Quick answer: Thomasi is a variety of uromastyx. Everything on this page is uromastyx-level guidance — we do not invent variety-specific numbers.

The care below is uromastyx-level guidance from our species hub, sourced to Merck Veterinary Manual — Exotic & Laboratory Animals: Reptiles and RSPCA — Reptile care advice. It applies to Thomasi exactly as it applies to every other uromastyx variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.

Heat first: the basking rock is the whole species

Basking surface 45–50°C measured with an infrared thermometer on the rock itself, ambient warm end 35–38°C, cool zone 24–27°C, nighttime drop to ~22°C. Heat comes from basking bulbs over flat stone (never heat rocks — burn risk); UVB T5 10–12% across the basking area. Humidity low (20–35%); a humid hide is unnecessary and can cause respiratory issues. A 120×60×60 cm enclosure suits an adult ornate; Egyptians need half again bigger.

Diet: weeds, seeds and zero insects

Greens and weeds daily: dandelion, endive, escarole, mustard, bok choy leaves, squash, plus dry seeds and lentils (a small dish a few times weekly — uros hull them like tiny machines). Occasional millet spray as enrichment. No insects: uromastyx are herbivores and animal protein damages kidneys over the years. Calcium + D3 supplement on food 2–3 times weekly for young animals, weekly for adults with strong UVB. Fresh water dish — they get most moisture from greens, but offer it anyway.
