Christmas present [I Christmas]

My two year old finally told me what she wanted for Christmas and it's not something I can give to her....
She came to me ten minutes ago and said mummy can we have a cat for Christmas. Told her we'll see what happens
I was wanting to get her a pet for a long time we had one when she was a baby but she passed, but unfortunately we cannot have one. Boyfriend said she'd forget about it on Christmas as she'll have her toys
