The Cat Tree is a single-objective quest given to kick off the Rafael's Courtship seasonal event. I don't know about your alliance, but many of the folks in my alliance are cat lovers, so we were really excited about getting this one! We were all refreshing, rebooting and even switching machines in an effort to make it come up for us. As soon as you place the Cat Tree and complete this quest, you are given the Cats in a Tree questline, also by Rafael.
Place the Cat Tree on your kingdom
