My dh has Chessie and he is big, he also has a lap cat. Snuffy found the cat as a kitten. We have had her ever since. We have her and two of her off spring. We are done with the off spring kittens. Two of the cats walk with dh when he walks the dog. The older one did it when he walked Snuffy and she does it when he walks Chessie. One of her off spring does it also.  Its funny to see him going down the road with the dog and two cats following him. The cats had no issues moving, they are mostly outdoor cats. They didn't try and go back.

Reality is determined not by what scientists or anyone else says or believes but by what the evidence reveals to us.
