they are an amazing amount of work. I think most people up for that work get toddlers instead.
loved them when I had them, no longer have the energy.
the leash was always more a reminder there were limits than any sort of control option. throw that weasel in reverse and the harness pops right over the head and he's free.
Honest semi related question. How far down in the kingdom goes personal recognition of self? Does the squirrel see its reflection and think, "mmmhm, slay gurl," or is that high order dolphin/elephant stuff?
I think scientists try to figure this out all the time, that's why we see headlines about dogs or dolphins or octopuses (octopodes?) being as smart as toddlers. We used to think pigs were dumb, but now we know they are quite intelligent. So I don't think there is a definitive answer to your question yet.
