Instead of trying to think of just any animal, I found it easier to add a constraint…

1. Animal that starts with A

2. Animal that starts with B

3. Animal that starts with C

…

(I also appreciated the easter eggs: “Are you Australian?” and “You listed both dingos and dogs, so I gave you the benefit of the doubt, but there's disagreement on whether the dingo is its own species of canid, a subspecies of grey wolf, or simply a breed of dog.”)
