Very nice job! And it look's like Xena couldn't be happier. That was nice of your dad and it looks to be a great sturdy, fun and comfortable cat tree. :bigthumb:
My brother and his wife have a new puppy, and we got Xena. My parents have resigned themselves to realizing those are the only "grandbabies" they are going to get LOL. So they have taken to spoiling them, wanting to spend time with them etc.
