Jaguar. Looks like a big heavy male. For those who - like me - have a hard time determining which is a Jaguar and which is an African Leopard, this is lesson one - Jaguars are bigger, and at full growth are heavier in the bone and muscle (especially the neck and head) than Leopards. If the pelage is visible Leopards have "rosettes" that are usually open, or broken somewhere in the circle. Jaguars have closed rosettes with spots inside.
A Jaguar cub stands next to its mother... A mother always protects her cubs no matter what! She stalks her pray and when the moment is right she strikes! She is dangerous she is fast she isn't one to play with. You don't mess with what is hers without suffering her wrath, you pay the consequences for toying with her.
