I decided to see what Sid would do when I filled the sink with a bit of water. He slithered down into it and drank. He then slithered to the edge after he was done and kinda headed down but stopped. Water poured/dripped out of his mouth. Is there anything I should be worried about? First time I've seen him do something like this, but I never caught him drinking before, so, just curious. Thanks in advance.
