Well if Sheldon Cooper from the Big Bang Theory were to be some animal I am sure he would be a cat. Why do you ask? Well first of all he is very intelligent and so is a cat and secondly a cat is just like him when it comes to not sharing his place in the house. For instance here too the reason why the cat is staring at the plant is because that was the cat's place before the new plant came in. Hahahaaahahhahahaahah
