Proper feeding is an important part of reptile care. The appropriate diet depends on the species, age, size and natural feeding behaviour of the animal.
Some reptiles primarily eat insects, while others may eat plants, animal-based foods or a combination of different foods. Before developing a feeding routine, it is important to understand the natural dietary requirements of the particular species.
Understanding Your Reptile’s Diet
Reptiles have very different dietary requirements.
Some species are primarily insectivores, while others are herbivores or omnivores. Even closely related animals may have different nutritional requirements.
A feeding routine should therefore be based on the species being kept rather than using the same diet for every reptile.
Choosing an Appropriate Feeder Size
For insect-eating reptiles, feeder size matters.
Young and small reptiles generally require smaller feeders, while larger animals can consume larger prey. Feeders that are too large may be difficult for an animal to capture or consume.
The animal’s actual size and feeding ability should be considered when selecting live feeders.
Variety in Live Feeders
Different feeder insects have different characteristics.
Silkworms, hornworms, mealworms, superworms, black soldier fly larvae, crickets and other feeders vary in size, moisture content and body structure.
Offering appropriate variety can prevent a feeding routine from depending entirely on one feeder type.
The appropriate feeder combination depends on the reptile being kept.
Gut Loading
The condition and diet of live feeders can also be important.
Gut loading generally refers to feeding suitable nutritious food to feeder insects before they are offered to the reptile. The goal is to provide well-fed insects rather than feeders that have been kept without appropriate nutrition.
Different feeder species have different care and feeding requirements, so their needs should also be considered.
Supplements
Depending on the reptile species and its overall diet, calcium or other supplements may be required.
Supplement needs can vary according to species, age, diet, UVB exposure and other factors. More supplement is not necessarily better, so supplementation should be based on the requirements of the animal being kept.
Feeding Frequency
There is no single feeding schedule suitable for every reptile.
Young, rapidly growing animals may have different feeding requirements from adults. Species, activity level, body condition and the type of food being offered can also affect feeding frequency.
Research the appropriate feeding schedule for the particular species rather than relying on a universal schedule.
Water and Hydration
Hydration is also part of reptile nutrition and care.
Different species obtain water in different ways. Some readily drink from a water dish, while others may obtain part of their hydration from food, misting or water droplets within their environment.
Fresh water and appropriate humidity should be provided according to the requirements of the species.
Monitor Body Condition and Feeding Behaviour
Regular observation can help identify changes in an animal’s normal feeding behaviour.
Pay attention to appetite, body condition and the animal’s ability to capture and consume its food.
A sudden or prolonged change in appetite can have many possible causes, including environmental conditions, stress, seasonal behaviour or health concerns.
A Balanced Approach
Good reptile nutrition involves more than simply offering food.
Appropriate feeder size, variety, feeder quality, hydration, environmental conditions and species-specific nutritional requirements all work together.
Learning about the natural diet of the reptile is the best starting point for developing an appropriate feeding routine.
