The Iguana

Living in the jungle as I do,you develop certain rules for critters who invade your house.
In my case they are :
Snakes and scorpions, instant death.
Birds and butterflies caught and set free.
Toads and frogs captured and reassigned different living areas ( the jungle )
rodents and geckos and ants, some kind of symbiotic existence.
But iguanas
it never was a problem till to-day when some scared, confused and not so small iguana suddenly came barging into my house causing wild havoc with the worthless ones in hot pursuit.
Once it got out of a window and, confronted by the mass of snarling and salivating mutts, decided to enter the house again and had me in a tizzy warding off the worthless ones with a broom whilst trying to make the iguana make a run for the open door.
It chose to attack the broom.
Well now, thought I, this calls for drastic measures, and grabbed the tongs from the kitchen and grabbed the now exhausted iguana with the tongs and carried it, with the mutts attacking me, out to the lower deck, and then with a flick of the arm, sending the culprit out in the jungle, only, it ended up in a tree.
So now guilt came crashing down on me....had I squeezed it too hard with the tongs and crushed its ribs ? had I , because I really, really don't like them, let my dislike get the better of me and deliberately squashed it ?
because there it was, just hanging from a branch of a tree.
I even fought my way through the jungle to the tree to check the creature who was still breathing.
And now, after many checks on the condition of the iguana it has finally moved and is now sitting in the tree, a little more alert.
Which then leaves me with the question
What does one do if an iguana enters your house ?
