Cat?

Lily did the funniest thing last night. She loves George and will try to say his name, and we've been trying to get her to say dog... which comes out as "DA!", but she will do it when she sees Georgie. But last night when we'd say dog, she responded with something totally different. Can't figure out if she's trying to say the G sound at the end of dog, but she ends up saying something that sounds a lot like cat. We don't have a cat, and I can't recall how she could have picked up on the word. Maybe this is an indication that she has in fact inherited the stubborn streak that both her mom and dad have? We're not sure, but it seems like Lily definitely knows her own mind, despite her young age!
