Sorry, I should have elaborated. Here is the hop bill from the pale ale I made. I like it (cat piss and all!). I meant to stick to amarillo and simcoe, but I ran out of amarillo. I've used all the other hops below, a lot, except for the simcoe. The cat box flavor / aroma was very real. It was my first thought upon drinking my first one.
