Gresham Pet Supply Pet Care Guide
Uromastyx
Uromastyx spp.
Why We Love Them: Uromastyx are the ultimate desert lizards. They are one of the very few strictly herbivorous lizards, meaning you never have to deal with live bugs! They come in spectacular colors (bright yellows, oranges, and reds) and have a heavily armored, spiky tail that looks like a medieval weapon.

The Protein Warning (No Bugs!)
HERBIVORE: Do not make live insects (crickets, mealworms) part of a Uromastyx diet. Zoo Med describes them as "mostly herbivorous with the occasional insect as a treat", so even the maker treats insects as a rare extra, never a staple.
Housing & Enclosure
Enclosure Type & Size
- Size: They are active foragers and need plenty of floor space. Ask our reptile staff to help you pick a size.
- Type: PVC enclosures, wood enclosures, or large glass terrariums with screen lids.
- Solitary: House them individually. They are highly territorial and will brutally fight for the best basking spots.
Substrate
- Recommended: Because they love to dig burrows to escape the extreme heat, provide a deep layer of dry, sandy substrate that holds a burrow. A mix of organic topsoil and play sand is excellent.
- Avoid: Calcium sand (can cause a blockage) and any moisture-retaining substrates (coconut fiber, cypress mulch).
Décor & Enrichment
- Basking Platform: Provide flat, dark slate rocks stacked securely. Slate absorbs heat perfectly.
- Hides: Provide tight-fitting hides on both the hot and cool ends of the enclosure.
Heating & Lighting
Uromastyx are the ultimate sun-worshippers. They require hotter temperatures than almost any other reptile in the pet trade.
Temperature Requirements
Zoo Med says desert baskers "usually require very hot basking temperatures of 100°F or more". Give them a very hot basking spot at one end and a cooler end to retreat to. Follow the label on your heat lamp and thermostat.
- Heating: Halogen basking bulbs are the usual heat source. Put the heat on a thermostat or dimmer.
- Measurement: You must use an infrared temperature gun to measure the surface of the rock. A stick-on wall thermometer will only measure ambient air and is useless for this species.
Lighting & UVB (CRITICAL)
- UVB: They live under the blistering desert sun. Without strong UVB, they can't use calcium properly. Use a linear high-output UVB tube over the basking area (Arcadia names uromastyx on its Desert 12% lamp), at the distance on the lamp's packaging. Replace it on the bulb's schedule.
Humidity & Water
- Target Range: As dry as possible.
- Water: Uromastyx have evolved to extract all the water they need from the plants they eat. A standing water bowl left in the enclosure raises humidity, so it is best to not keep one in. If you offer water, use a small dish now and then and take it back out.
Diet & Nutrition
Greens & Vegetables (the main food)
- Staples: Dandelion greens, turnip greens, mustard greens, escarole, endive, and cactus pads (nopales).
- Avoid: Spinach (binds calcium), iceberg lettuce (no nutrition), and kale (in large amounts).
Seeds & Lentils
- Provide a shallow dish of dry lentils, split peas, and bird seed (white millet). They love to crunch on these, and they provide essential plant-based proteins.
Supplements
- Zoo Med says "Repticalcium without Vitamin D and Reptivite with D3 should be added to both live and plant food as directed." Follow the powder label for how often.

How We Keep Them at Critter Cabana & Gresham Pet Supply
- Beating Dry Oregon Furnace Air (and Summer Heat Spikes): Across the Willamette Valley and Portland Metro, running the house furnace all winter drops indoor humidity to 25–35%, which quickly causes stuck sheds and dehydration in screen-top tanks. Uromastyx are the exception: they need a dry enclosure, so our crew uses dry, sandy substrate, no humid hide and no standing water bowl. We never mist their enclosures.
- Thermostat & Linear UVB Standard: Every heating element in our Newberg and Gresham reptile rooms runs on a thermostat or dimmer, with a very hot basking spot and a cooler retreat, and the heat and UVB lights run on a day/night timer. In summer, if an upstairs room climbs above 82°F, a dimming thermostat automatically backs down the basking lamp so the cool side never overheats.

Common Questions (FAQ)
What size tank does an adult Uromastyx actually need?
An adult Uromastyx needs plenty of floor space, with a very hot basking spot at one end (Zoo Med says desert baskers usually need 100°F or more) and a cooler end to retreat to. Our reptile staff can help you pick a size.
Does my Uromastyx need extra humidity during dry Oregon winters?
No. Uromastyx need a dry setup. Use dry, sandy substrate, skip coconut fiber and cypress mulch, don't mist, and don't leave a standing water bowl in the enclosure.
What is the best bioactive clean-up crew for a Uromastyx?
Uromastyx need a dry setup, so a moist soil and leaf-litter bed is the wrong choice. Ask our reptile staff before adding any clean-up crew. Our 1-Page or Tri-Fold Bioactive Substrate Recipe Guide covers the rest.
