Reply To: Squirrels vs Cats

well squirrels used to go up trees but they could never come down again

so after a million years of squirrels stuck in trees, some cosmic rays, mutations, and other birth defects decided in their wisdom to create an unbelievably complex ankle system of tarsals metatarsals muscles nerves, and a brilliant arrangement of tendons that allow the back ankles to turn around 180 degrees and operate under complete control in the exact opposite direction that the ankles turn to go up the tree!

Evolution apparently decided the cats did not deserve such an arrangement, after consulting with some mice.
