The specific days for crocodile turtles to digest food depend on their living environment and growth stage. If they are young turtles, their digestion speed is relatively fast, so long as they are fed according to their normal appetite, they can be digested in about one day. As adults, crocodile turtles' digestion ability will decrease, but their appetite will become larger, so the digestion time will be longer, and it will take about 2-3 days to digest. In addition, the water temperature in which they are raised also has a great influence on their digestion speed. If the water temperature is on the high side, they will digest faster. If the water temperature is low, the digestion rate will slow down.

Snapping turtles are omnivorous animals, but they like animal feed best. Breeders can feed them more small fish, shrimps, earthworms, loaches, tadpoles, lean meat, animal viscera, insects, shellfish, snails and so on. These foods contain a lot of fat and protein, which can meet most of the nutrients needed for their growth and development. However, breeders should regularly feed them some plant feeds. The plant feeds suitable for them include cabbage, rape, lettuce, water spinach, apples, bananas, grapes, etc. These foods contain a lot of vitamins and trace elements, which can enhance their resistance and immunity.
