The only time Ive ever seen drops of liquid coming out of the cloaca was on a young and very malnourished, dehydrated chameleon. It was so skinny I thought it was a female until I took him in and got him healthy and now he is a big beautiful blue nosybe. He would try to pass a bowel movement but all that would come out was liquid then he would sleep during the day. Is yours eating and drinking normally? Is it sleeping during the day?
