Well, we had a bit of a containment incident with the poison dart frogs today 
Apparently they are now large enough, strong enough and inquisitive enough to both move the plastic flap at the edge of the lid of their enclosure, AND to crawl through the resultant opening in search of adventure
Stumbling through my living room this morning pre-coffee and I'm greeted to the sight of one of them, I believe it was the male, scaling the wall above their tank with his sticky little frog feet Mission Impossible-style, like so
Miraculously he sat still while I approached and he basically let me scoop him up - I think he was smack in the middle of the realization that the world outside the tank is not at all like the world inside the tank
I thought for sure he'd leap off the wall and end up behind some piece of furniture and it would be a race for his life between me, my cats, and the low humidity in the house
But I got him back in the tank, and for the time being the walls of the Fortress of Frogitude have been reinforced with several volumes of the Oxford English Dictionary -- a prison of words he does not understand -- until I figure out a better security system
(seriously, if anyone on frog twitter has advice for quelling a frog uprising I'm all ears, they are a little over a year old now and neither has shown any interest in The World Beyond The Glass until today)
I should also note that poison dart frogs *are not poisonous* in captivity. Their toxins derive from their diet, and their captive diet doesn't contain the compounds that make them poisonous in the wild
Also, while the frogs were carrying out their devious plan this little jerk just sat quietly on his log next door, watching it all go down and saying NOTHING
