This sounds totally nuts, even to me. Been a cat daddy to some sweet feline friends for 20+ years. Started brewing maybe 3~ish years ago, and noticed at some point that certain hops had a "catty" aroma. Years go by, several dozen batches of IPA's, etc. Fast forward to now. Our recent rescue cat, Milo, a prodigious peepee factory, his litterbox disgustingly but not altogether unpleasantly reminds me of galaxy, mosaic, and el dorado hops, if you take my meaning. Am I weird, are those hops weird, or is my cat a beer God?
Guess you know you're a homebrewer when scooping the litterbox makes you think about brewing an IPA.
