All PZ felines are created to see a cute face. If the other animals are close enough to their natural appearance, the cats are as if taken from a cartoon. They have very human expressions and a face that makes them as easily integrated as possible with what human recognize as human expressions. Cats have surprisingly many facial expressions, depending on their behavioral involvement, but their facial expressions never have anything in common with human facial expressions because they cannot have the same emotional feelings as human ones. Any such approach is found only in cartoons. Maybe cats are ferocious, and this behavior is associated with the difficulty of obtaining food in the wild, for me Frontier felt the need to make them more sympathetic to human perception. Hence the deformation of the models of lions, tigers, jaguars, snow leopards, cheetahs, is expression to make them more acceptable to sensitive players.
