Egyptian Uromastyx (Uromastyx aegyptia)
Moroccan Uromastyx (Uromastyx acanthinura)

In their natural habitat, Uromastyx are diurnal and spend much of their time basking in the sun and foraging for vegetation.

Uromastyx Care: Creating the Ideal Habitat

Providing a suitable enclosure is crucial for the health and well-being of your Uromastyx:

Enclosure Size:

Minimum size for an adult: 4 feet x 2 feet x 2 feet (120 x 60 x 60 cm)
Larger enclosures are always better

Substrate:

Use a mixture of sand and soil, or specialized reptile sand
Provide a depth of at least 4 inches for burrowing

Temperature Gradient:

Basking spot: 120-130°F (49-54°C)
Cool side: 80-90°F (27-32°C)
Nighttime temperature: Can drop to 70-75°F (21-24°C)

UVB Lighting:

Essential for vitamin D3 synthesis and overall health
Provide 12-14 hours of UVB exposure daily

Humidity:

Maintain low humidity levels, around 20-30%
Occasional misting can be beneficial for shedding

Hides and Decor:

Offer multiple hides and basking platforms
Add rocks and branches for climbing and nail wear

Water:

Provide a shallow water dish, but many Uromastyx prefer to get moisture from their food

Diet and Nutrition

Uromastyx are herbivores, requiring a diet high in fiber and low in protein:

Leafy Greens:

Collard greens, dandelion greens, mustard greens
Bok choy, endive, escarole

Vegetables:

Squash, bell peppers, carrots (in moderation)
Avoid high oxalate vegetables like spinach

Flowers:

Hibiscus, dandelion, nasturtium

Seeds and Grains (in moderation):

Lentils, millet, quinoa (sprouted)

Supplements:

Calcium supplement 2-3 times per week
Multivitamin once a week

Feeding Schedule:

Adults: Feed daily or every other day
Juveniles: Feed daily

Common Health Issues

While Uromastyx are generally hardy, they can face several health issues:

Metabolic Bone Disease:

Caused by calcium deficiency or improper UVB lighting
Symptoms include soft bones, tremors, and lethargy

Respiratory Infections:

Often due to incorrect temperature or humidity
Symptoms include wheezing, open-mouth breathing, and nasal discharge

Impaction:

Can occur from ingesting substrate
Symptoms include loss of appetite and difficulty defecating

Parasites:

Both internal and external parasites can affect Uromastyx
Regular fecal exams by a veterinarian are recommended

Can occur from overfeeding or providing too many fatty seeds
Maintain a balanced diet and proper enclosure size for exercise

Regular check-ups with a reptile veterinarian experienced in Uromastyx care are essential for maintaining your pet’s health.

Behavior and Handling

Understanding Uromastyx behavior is key to successful ownership:

Basking: Spend much of their time basking under intense heat.
Burrowing: Enjoy digging and creating burrows in their substrate.
Tail Use: May use their spiny tail as a defense mechanism when threatened.
Social Behavior: Generally solitary, but some species can be kept in pairs or small groups if introduced properly.
Handling: Can become quite tame with regular, gentle handling, but should always be supported properly.
