What Causes a Pacman Frog to be Overweight?

Frogs that are kept in captivity are prone to suffering from obesity. The Pacman frog is a lazy frog, an opportunistic eater that eats anything that comes past it that is smaller than itself.

In captivity, they eat without regard for the energy they need, which leads to obesity.

If you are unsure if your frog is overweight or healthy, there are some signs that could help you identify you have an obese Pacman on your hands, this includes:

  • Lethargy
  • Struggling to move
  • Problems with respiratory system
  • Excess body weight is visible

It’s not uncommon to come across an overweight Pacman frog. They have insatiable appetites and they will eat when the opportunity knocks, whether they are hungry or not. These are inactive frogs that tend to bulk up just before breeding season.

In captivity, it’s you job as a responsible amphibian pet owner to provide your frog with a varied diet. The endless supply of prey can lead to your frog becoming overweight.

It’s uncommon to see a young Pacman frog being overweight, as they use the extra calories to aid in their growth. Adult frogs, on the other hand, can become obese within months.

Being overweight is exceptionally dangerous for your frog and can result in a host of health issues.
