What kind of animals have huge appetites?

Many animals like to eat alot but here's a few:

Panadas need to eat for about 14 hrs a day in order to consume the nutrients from their favorite food (it's 98% of their diet) Bamboo.

Grizzly bears eat alot of food in order to survive the long winter while hibernating.

Tigers & Lions can gulp down about 50 pounds of food a day.

Hope it helps!
