We have a cat that eats potato chips and cashews she also drinks beer. My macaw will drink beer (I don't let him have much) he won't eat oranges,carrots, green beans he'll crush them in his beak and drink the juice when he's done it's almost like they're dehydrated.
In college my roomate got a iguana. The thing seemed to like me so he would hang out on my shoulder while I wateched TV. He would walk down my arm and drink my beer or bourbon. When he started getting cold and I would put him back in his tank he would be leaning at about 45 degrees. He was a mean drunk though.
