Lizard in the Trash

My hubby was sitting out on the patio the other evening and heard a strange noise. He finally tracked it down to a rustling in the trash can. When he looked he saw a lizard in the sack that is in a plastic basket type trash container. Poor thing in their with hubby's stinky cigerate butts and ashes. After taking it's photo we released it into the garden. We have no idea how it got there. Did one of the cats put it there? Or did it manage to climb into the container? Seemed an odd thing for a lizard to be climbing if that is how it got there.
