iguana is acting funny

Question
my iguana got into the window sill and got really cold we thought he was dead but we tried to warm him up and he is alive. now hes not very active and is twitchy and he bit his tongue. i was wondering what could be wrong with him and if there is anything we can do until we can get him to a vet

Answer
Hello Cody,

Oh poor thing, how long was he in the window sill?  
Did you put him in warm water to bathe him?  That really helps to warm up their core temperature.  Do you have a ceramic heat emitter or a heating pad?  I don't usually recommend heating pads, but, in this instance, if you don't have anything else, get a towel & put that in between the heating pad & your iggy so it doesn't get too hot.  Try to keep him warm all night long until you can get him to a vet.  
Iguanas are very sensitive to cold.  Do try to keep him warm overnight.  Let me know how he is doing!
Have you given any tepid water to him?
