For those of us who have been playing this game for a while expanding is a pivotal decision that can really impact your game. It used to be that I would purchase each new "type" of habitat that came out. I have the Halloween, Christmas, Valentine's Day and St. Patrick's Day habitats. I finanally am able to expand and my first thought was to purchase the new Cosmic habitat. I am so happy I resisted the urge to purchase this habitat as I have only managed to breed only the Plutopus and would have been sitting on a habitat with only one inhabitant. Even my husband who usually has the magic touch with creature breeding cannot breed the elusive kitty. I decided to purchase the water habitat instead and am happy that I did.
