... Sneak up on Elsa (F3 Savannah who are not familiar with her). Her hearing is just too sensitive... She hears every little noise... It would be nice to be able to get a pair of hear plugs for them, so that you can do something and not having found out what you were doing 5 minutes before you were doing it. I would say she could hear a "Gnat" expel gas from 50 yards away... On a Tile Floor, down stairs with socks on being as quiet as I can, she will be looking at exactly where I will be and I mean not even close to her...
