Savannah Monitor Care Sheet

The Savannah Monitor (Varanus exanthematicus) is one of the most recognizable monitor lizards in the reptile hobby. Native to the grasslands and savannahs of central and western Africa, they are intelligent, powerful, and highly food-motivated animals that can develop strong relationships with their keepers over time. Their stocky build and calm disposition often lead people to believe they are an easy beginner monitor, but in reality they require very large enclosures, intense heating, and a commitment to providing a healthy lifestyle. With proper husbandry and regular interaction, Savannah Monitors can become confident, inquisitive reptiles that are incredibly rewarding to own for experienced keepers.

Care sheets are only to be taken as guidelines. Just as with all animals, each reptile will have unique traits and personalities special to the individual animal that may require adaptation in their husbandry and care. The following care sheet will address basic requirements but as the primary caretaker of your pet, we encourage you to take notice of your pet's behaviours and preferences and make adjustments as they grow with you and your family. Please also keep in mind that unlike mammals, most reptiles change their behaviour according to the weather seasons even if you keep them indoors all year round.

We keep lizards in stock at our Toronto store and ship across Canada.

Enclosure: Savannah Monitors grow into large, muscular lizards that require considerably more space than many first time owners anticipate. Juveniles may temporarily be housed in a 40-gallon enclosure while they are small, but adults require a custom enclosure measuring at least 4' x 2' x 2'. Larger is always encouraged. When selecting an enclosure, remember that size alone does not guarantee proper husbandry. A monitor needs a properly heated enclosure with multiple basking areas, deep substrate, hiding places, and enrichment. An enormous enclosure without sufficient heating or furnishings is far less beneficial than one that has been thoughtfully designed. Unlike many reptiles that spend much of their day resting, Savannah Monitors remain active and curious, spending their time exploring, digging, basking, and searching for food.

Substrate: Providing deep substrate is one of the most overlooked aspects of Savannah Monitor husbandry. These lizards spend much of their lives digging extensive burrows that provide security, humidity, and temperature regulation. We recommend substrates such as Zoo Med Forest Floor for beginner keepers, while advanced keepers often create naturalistic mixtures using Reptisoil, excavator clay, sand, and organic soil. Exo Terra Stone Desert also creates excellent naturalistic environments. The substrate should ideally be deep enough to allow at least partial burrowing, with adults benefiting from 12-24 inches whenever possible.

Temperature & Humidity: Savannah Monitors are highly tolerant to high temperatures and can withstand short exposures of up to 140°F. Comfortable surface basking temperatures should reach 95-110°F (35-43°C) while the surrounding warm side remains around 90°F (32°C) and the cooler side between 80-85°F (27-29°C). Nighttime temperatures can safely fall to approximately 75-80°F (24-27°C). Although often described as desert animals, Savannah Monitors naturally spend much of their lives inside humid underground burrows. For this reason, we recommend maintaining overall enclosure humidity between 40-60%, while ensuring deeper substrate layers retain additional moisture for burrowing. A humid underground environment greatly assists with hydration, healthy sheds, and overall respiratory health.

Lighting: High output UVB lighting is essential for Savannah Monitors. Provide UVB lighting for approximately 10-12 hours daily using high quality reptile specific bulbs. Because of their large size and intense heat requirements, multiple heating devices are usually necessary. Basking bulbs, halogen flood bulbs, ceramic heat emitters, and deep heat projectors are all excellent choices depending on enclosure size and room temperature. As the enclosure becomes larger, additional heat sources are almost always required to establish proper temperature gradients.

Decor: Savannah Monitors are intelligent animals that thrive when given opportunities to interact with their environment. Provide large logs, sturdy branches, elevated basking platforms, heavy rocks, cork bark, tunnels, and secure hiding places throughout the enclosure. Although they are primarily terrestrial, juveniles especially enjoy climbing opportunities. All decor should be extremely stable. Savannah Monitors are incredibly strong and can easily topple lightweight decorations while digging or exploring. Enrichment is just as important as proper temperatures. Rearranging decor occasionally and offering puzzle feeding opportunities can provide valuable mental stimulation.

Feeding: One of the biggest misconceptions surrounding Savannah Monitors is their diet. In the wild, they consume primarily insects and other invertebrates, with only occasional vertebrate prey. Captive diets that rely heavily on rodents often result in obesity and shortened lifespans. A healthy diet should consist primarily of insects including crickets, roaches, grasshoppers, superworms, mealworms, hornworms, silkworms, butterworms, black soldier fly larvae, and the occasional snail when available. Gut loading feeder insects before feeding significantly improves their nutritional value. Well fed insects produce healthier monitors. Occasional pinkie mice, quail eggs, chicks, or lean raw meats and organ meats may be offered in moderation, particularly for larger adults, but these should not become staple foods. Providing dietary variety is far more beneficial than feeding large amounts of one prey item.

Supplementation: Lightly dust insects with calcium supplements on a regular basis while also offering a reptile multivitamin periodically. When quality UVB lighting is provided, excessive Vitamin D3 supplementation should be avoided.

Water: Fresh clean water should always be available in a sturdy dish large enough for soaking. While Savannah Monitors may not soak every day, many individuals enjoy occasional baths, particularly while shedding or during warmer months. Water should be changed daily.
