White-Throated Monitors (Varanus
albigularis)
White-throated monitors are
found throughout the
savannahs of southern
Africa. They prefer termite
mounds or burrows and they
are most active during the
wet season when food is
abundant. White-throats are
a large powerful lizard and
reach six feet in length.
Wild white-throat monitors
will eat any animal they can
overpower and are immune to
some types of snake venom.
Captive breeding is somewhat
common and large females can
lay fifty eggs each year.
Babies will hatch within 180
days and are much more
colorful than adults. With
proper care white-throat
monitors can live over 20
years. Prehistoric Pets
promotes responsible reptile
ownership and we recommend
locking cages that prevent
accidental escape. Large
monitors and other escaped
reptiles can have a negative
impact on the general public
which can lead to a ban of
reptile ownership.
Temperature and UV
Lighting
White-throat monitors should
be maintained between 85-90
degrees with a basking spot
of 95 degrees. At night the
temperature can drop to 70
degrees. Hours of daylight
should be 12L/12D during a
24 hour period. Humidity
should also be maintained
above 65%. UVB lighting is
not a must for monitors, but
is recommended. UVB
lighting enables reptiles to
metabolize calcium, by
creating Vitamin D3.
However, because their diet
consists of rodents and
other live prey, they can
usually receive enough D3
and calcium through their
diet. The bones of the prey
will provide calcium, while
the liver will provide
Vitamin D3. Also it is very
important to change your UVB
light every 6-8 months,
after this time the light
stops producing adequate UVB.
If you’re not sure if your
UV light is still producing
UVB, bring it in and we’ll
be happy to test the light
for you.
Housing
Baby white-throat monitors
can be kept in a 29 gallon
cage but they grow quickly
and will soon need larger
housing. Adult monitors
should be kept in a cage
that is at least 6’ x 4’.
Extremely large specimens
may require room sized
enclosures. Ideally, the
cage should include multiple
hiding spots to provide a
sense of security.
Bedding
Our recommendation for
bedding is bark or some type
of mulch. This type of
substrate holds moisture
very well, allowing a higher
humidity. Even though they
are from Africa, they are
not a desert species. Cages
that are too dry can cause
dehydration and shedding
problems. We also recommend
that you mist the bedding
several times a week to
increase humidity.
Food
White-throat monitors are
opportunistic hunters and
are known to eat almost
anything. Ideal foods are;
mice, rats, fish, crickets,
superworms, nightcrawlers,
beef heart, and hard boiled
eggs. A mixed diet of these
food items, four to five
times per week, is ideal and
will ensure proper growth
and health.
Calcium
A calcium and vitamin
supplement should be put on
all food that does not
contain bones. When feeding
your monitor mice, rats, or
fish, no supplement is
needed.
Cleaning and Handling
The terrarium should be
cleaned as necessary. Any
fecal matter or left over
food should be cleaned out
several times a week. The
bedding should be completely
changed once a month and
fresh clean water should be
provided at all times. The
inside of the terrarium can
be cleaned out with an
appropriate reptile cage
cleaner, we recommend
Natural Chemistry’s Healthy
Habitat. White-throat
monitors can be handled on a
daily basis and always wash
your hands before and after
handling them.
