Easy Questions With Hard Answers

So last night there I was drinking my iced coffee when Kody plops himself onto my bed wanting to hang out for a little while.  He asked for a sip of my drink and of course I let him have a small sip.  After telling me it tasted good,  it had some hazelnut creamer in it, he asked why he isn't suppose have caffeine.  You see his heart works on over drive all the time, even when he is sleeping, so adding in something like caffeine would make things compound and his heart is already working like a race horse .. so that is why no caffeine.
