In the wild, frogs can survive for months or years without eating. They can do this because they have a slow metabolism and store energy in their bodies.
They also don’t need to drink much water because they soak it up through their skin. They can also convert carbon dioxide into oxygen.
However, in captivity, frogs need to be given food on a regular basis. They also need to be fed a variety of different foods because they are omnivores and can’t just eat one type of thing.
Depending on the species and size of a frog, they can all go a certain amount of time without eating. This is in part due to how they are able to digest their prey.
Larger frogs can typically eat larger prey such as mice, which takes longer to digest and can help them go a bit longer before they start to feel hungry again. Smaller frogs, on the other hand, are more likely to need their next meal faster.
Healthy adult frogs can generally go 3 to 4 weeks without food before they need to eat again. If your frog is not getting enough food, you can try to find someone who has a stockpile of live insects in their area and see if you can arrange a shipment. Or you can purchase more food from a pet store or online. Just make sure you don’t overfeed your frog.
