Well, Cas is going to the vet tomorrow morning. He's got a UTI. He seems to go longer and longer between getting them, but I wish the urinary health food he ate was enough to just keep him healthy all the time. But I'm also glad that I know what to do and what to expect when he gets an infection. (Answer: don't go to the emergency vet unless paying many hundreds of dollars is an option.)
I think I'm going to just have a chill night and watch some Chrono Trigger before bed.
