“What Did They Feed This Guinea Pig?”: 48 Oversized Animals That Have No Business Being This Big

Mother Nature doesn't always play by the rules... Sometimes she flips the script, hits Caps Lock and produces something so unusually large that it looks like it could be cast in a sci-fi movie.

We're talking freakishly giant animals that somehow manage to live pretty normal lives despite their above-average size. Think dogs that tower over the kitchen counter, 20-pound fluffy rabbits and the world's tallest donkey who stands at 68 inches high.

Some are the result of genetics, others have been bred to be big. A few simply defy logic and lack scientific reason. Despite being super-sized, many of these animals are super cute, and seem to be completely unaware that they're not tiny pets.

People have been sharing pictures of the times Mother Nature said "upsize, please!" and Bored Panda has put together a list of the best. Tell us your favorites by hitting the upvote button and be sure to weigh in with your thoughts in the comments section below.
