Agreed, leenia. Cats CAN jump....if they aren't terrified. They can't always land jelly side up though.

Fear of falling has kept me off ladders for years. I just can't do it. Might could to save an animal though. Climb and descend a ladder on the balls of your feet, NOT the arch or heels. Use the calf muscles to lift you UP and DOWN, not your knees.

Or, just JUMP! LOL

Just don't ask me to climb one of those 'pole cross' Anasazi ladders in the pueblos.
