Why Is Your Blue Tongue Skink Overweight?

Overfeeding

Not Feeding Them With Enough Vegetables.

Generally, a blue tongue skink requires 50% vegetables in their diet. Therefore, not feeding your skink enough vegetables can cause health problems like obesity as they will not get enough nutrients.

Not Providing Your Skinks With a Variety of Feeder Insects

Blue tongue skinks require 40% protein in their diet, and they get this nutrient from feeder insects.

However, your blue tongue skink can become overweight if you are not feeding them with various feeder insects. For instance, feeding your skinks with insects like hornworms, waxworms, or pinky mice will make them obese.

Not Enough Exercise

It is also possible for blue tongue skinks to get overweight if it is not getting enough exercise. For instance, a skink will not have enough space to explore and move around if you house it in a small enclosure.

Low Temperatures

Another reason a blue tongue skink becomes overweight is if you are housing it in an enclosure with a low temperature. This is because blue tongue skinks are cold-blooded animals and require enough heat to digest their food.

However, housing them in an enclosure with low temperature means they cannot process their calories properly, causing weight gain.
