The cats
After baking a cake I am hungry and since it's midnight I decide to have a snack. After some of my cake and two grilled cheese sandwiches I finish off my soda. I chugg the 1/2 liter remaining in the bottle VERY quickly and end up with a tummy ache. I am not very good with chugging, which is why I get that tummy ache moaning in pain, heavy breathing, and struggling to burp.
