Hi, DOC-
I saw your other post, too, and don't have an answer yet, but my ig is at the vet today, and I want to know how to weigh him, too. I'll ask and post about it later.
I'm thinking maybe one of those scales from the supermarket, you know, that you weigh fruit in, or from the deli! Actually, I once found a newborn-baby scale at a flea market. It was from a maternity ward, and dated back to the fifties or sixties. It would have been perfect... long plate to lay the baby on, would probably accomodate most, if not all of an iguana... too bad it didn't work. Another option I'm thinking of (not very realistic one for me, though)- my father owns a scrap metal yard, and he has a HUGE scale that is just a 4'x4' square on the ground that you set pallets of stuff on. It reads out on a little LED screen on the wall- I bet it can weigh anything, even if it's a big, squirming lizard!
