I have a lion head domestic adult male named Leon, he’s very lovey most the time, but just recently he has started acting strange. I got him a new hay feeder for Christmas and I refilled his water with good store bought stuff and he loved both he drank half the water and immediately started using his new Hay feeder but just a few hours later he started doing something he’s never done, he started digging at his a corner of his cage until there was nothing left but the plastic and then continued to scratch at it for a really long time, this seemed very strange to me so I watched him do it for a bit but I couldn’t see any reasoning behind it all. He ended up stopping for a good few hours then would gradually do it here and there until bed time, but around 3 am he was back at it again and this time with a passion, he has never done this before and I am concerned about it because he’s leaving scratch marks on his cage and he’s only focused on a certain corner. He’s eating just fine and he poops normal so is this a sign of anything or is he just angry at his cage or something else?
