I'm not familiar with the hibernation process that a frog goes thru. Just had a question as to why my pacman has had his eyes closed all day. Is it that he is hibernating or there another explanation as to why he is closing his eyes. He just started doing this maybe about two weeks ago. He is still eating and seems to be doing fine. Just would like to know all the possibilities as to why a frog would have their eyes closed all day.
