I love the ones with bunny butts!! I have two - one with a 2-3 inch curled tail and one with a one inch tail. They say you are less allergic to bobtial/Manx cats - dont' really know but I'm not allergic to these two which is great since I'm very allergic to cats. Arn't they so cute with their bunny butts!!! They are still cute when they are older too!! Debbie
