I have 2 places I keep my piggy... 1.) At night he's in his cage with a water bottle, food and igloo 2.) During the day he's with us in a playpen with a water bottle, food, hidey and some toys. I do this so I can keep him safe from our 3 cats while I sleep without always moving his cage. Nevertheless, he has 2 water bottles. He seems to drink more at night than during the day. He's about 6 months old. Is this normal? Maybe I just never see him sneak a drink but I feel like I don't fill up his play pen's water bottle much. So, how much water should he be drinking? Is there a way to see if he's getting enough? I know it's available and he's peeing/pooping fine, no other changes ... Maybe I worry too much LOL
