Sulcata Tortoise Not Eating
A Sulcata Tortoise that has stopped eating or reduced its food intake is one of the more common concerns keepers raise. In many cases the cause is an environmental or husbandry issue that can be identified and corrected. This guide covers the most likely reasons and what to check first.
Check Temperatures First
Temperature is one of the first things to check when a Sulcata’s appetite decreases. Tortoises are ectotherms — their metabolism, digestion, and activity levels are directly tied to ambient and basking temperatures. A tortoise kept too cool will slow down, reduce activity, and stop eating.
Check:
- Basking spot temperature: should be 95–105°F
- Ambient warm side: 85–90°F
- Overnight temperature: should not drop below 70°F indoors for extended periods
Use a temperature gun or digital probe thermometer rather than relying on ambient room temperature estimates. A tortoise that cannot reach an adequate basking temperature will not eat normally regardless of what food is offered.

Seasonal Slowdown
Sulcatas do not brumate the way Russian Tortoises do, but they can naturally slow down during cooler months, particularly if they are kept in a room with seasonal temperature fluctuation or exposed to natural light cycles. A mild seasonal reduction in activity or appetite can occur, but significant or persistent appetite loss should not automatically be attributed to the season. Continue monitoring food intake, body condition, activity, and temperatures.
New Animal / Recent Relocation
Newly acquired Sulcatas or animals that have been recently moved to a new enclosure commonly go off food for a period. Stress from relocation can temporarily reduce appetite, but illness should not be ruled out solely because the animal is newly acquired. Avoid excessive handling during the settling period and ensure enclosure parameters are correct.
Food Refusal vs True Anorexia
There is a difference between a tortoise that is declining specific foods and one that has stopped eating entirely. A tortoise that ignores one food but continues eating appropriate alternatives is different from one that refuses all food.
Consider:
- Has the diet recently changed? Sulcatas can be slow to accept unfamiliar foods.
- Is the tortoise being offered appropriate food? High-water, low-fiber items may be ignored in favor of hay or grass.
- Is the tortoise still active and alert when warm?
Other Husbandry Factors
Beyond temperature, other husbandry issues can contribute to reduced appetite:
- Inadequate UVB — ensure indoor animals receive appropriate UVB as part of their overall husbandry
- Enclosure stress — an enclosure that is too small, too exposed, or lacking appropriate hides and shelter can cause chronic stress and appetite suppression
- Dehydration — ensure fresh water is available and address the enclosure’s overall hydration and husbandry conditions; a lethargic or dehydrated animal should be evaluated by a reptile veterinarian
When to See a Vet
Consult a reptile-experienced veterinarian if:
- The tortoise has persistent appetite loss despite corrected temperatures and husbandry
- Appetite loss is accompanied by lethargy, discharge from the nose or eyes, wheezing, or changes in stool
- The animal appears to be losing weight
- There are visible signs of shell or skin problems alongside the appetite loss
Parasites, respiratory infections, and other health issues can all present as reduced appetite. A fecal test and physical examination by a reptile vet can rule out underlying health causes when husbandry corrections have not resolved the issue.
