Lyla is a cat and Lacee is a mouse. We didn't plan it that way which is weird. We bought Lacee that mouse outfit a month ago. Lyla was going to be tinkerbell at first then for some reason she started saying she was a kitty cat and would crawl around saying meow. I asked her if she wanted to be a kitty cat and she said a white cat. I thought a black cat would be more appropriate for halloween so thats what she became.
