As the newet PT members to get a CH kitty I have not done anything special for her. I already had 4 blind cats, so the house is designed so that they can climb up on what I want them to (because they can not see to jump up). So this has worked well for the newest addition. But I watch her and wonder how she doesn't end up full of bruises (I know I would ). But she loves to play with the other cats and run around the house. (She is only 3 months old so she is not quite big enough to learn how to do stairs yet but I am sure it will come with time and my heart attack )
