Not the pet but I've seen the Tiny Tot. Nothing to dislike except the lack of a window to watch the flame. Honestly I think Fastsco stoves are the best deal going. Their airtight and work well and aren't prohibitively expensive.
Here is a more expensive alternative that has a window to watch the flame, which is something I really want. BTW the Door on the Fatsco stoves is an ash door and is below the flame so no flame viewing there either.
