I ask this because I found a pink gecko in my bathroom today.
Pink didn't strike me as being the first color choice of your average gecko, so I slapped on the glasses and took a good look at him/her. Little cloverleaf paddy-paws, check. Big bulgy eyes, check. Black-ringed tail, check. Two inches from nose to tip of said tail, check.
It seems healthy and active. I'm afraid to catch it, because it looks so delicate. Besides, don't geckos' tails come off if you try to grab them? And couldn't I break a leg or some ribs or something?
So in the bathroom it stays. I'll put a plant in there later to give it some cover from the Evil Cat Who Eats All Small Creatures, and it already has plenty of water. I figure if I can keep it alive for a few more days, it might climb up onto a wall or some flat surface where I can trap it under a glass and then take it outside.
Sure is a cute little guy. I think I saw it flicking around the corner of the cabinet about two weeks ago--at the time, I wasn't sure whether it was a scorpion (unusual this far East, especially three stories up) or a lizard. I'm glad he's a lizard. A pink scorpion would've seriously screwed up my worldview.
