Dear Amelia & Zoe,
You are whippets. Whippets are hounds. Hunting little furries is what you do. Every walk we go on you spend most of the time looking for bunnies and squirrels. So, why, by all that's holy, when I show you the corner where I saw a mouse 10 seconds ago, do you both look blankly at me and go back to the sofa?
The exasperated one who must be feeding you too much!
