Reeses LOVES water bottles. When I finish drinking a 16 oz Dasani water bottle I will flatten it in the middle with my hand and put the lid on it. Reeses can amuse himself for hours. He eventually chews the lid off and works on the mouth of the bottle, at that point after he does a lil damage to the bottle mouth I take it and throw it away so he doesnt do any damage to his mouth. LOL!
