When I got my 2nd BP Cheetah, he had burns on his body from a hot rock. Though my BP's coloring on its belly were alot darker and had some actuall scarring from the burns, these pictures do look like burn marks. Cant say for sure but looks alot like burns like Marla said.

Does your BP seem a little stiff? Can he bend like he should be able to? My BP was unable to bend certain parts of his body due to the burns.
