Pick the pet, paste whatever you want them to react to, and tell the director what you actually think. The opinion is yours; the delivery is theirs. You can direct every shot afterwards.
What happens next. You add anything you want shown on screen, then the writer runs knowing what it has to work with. You will be able to read it, change the setting and camera on every shot, ask for rewrites, and approve it. Nothing is charged and nothing is filmed yet.
