When I get back in bed with my first cup of the day, the kitty typically gets on my lap and takes a big SNIFF of it. I’ve never seen another animal be consistently interested like that- I like to imagine she’s a reincarnation who really enjoyed coffee in a past life, and this is a simple reminder of that

PostScript: saw a bunch of notifications and immediately assumed I said something ridiculous elsewhere lmao.
Go to youtube and search “cat burying coffee”. There’s hundreds of videos of cats smelling coffee and instinctively trying to bury it like it’s poop or something.
Haha I think it’s because of the high volatile compounds - particularly more of the nitrogen (ammonia?) adjacent ones. So it literally has the “essence of cat pee”.
