to-do list under a stack of half-marked 2nd-year students' Herbology parchments ask Hagrid for advice on cats finally, an animal he doesn't care for. So much for that.
ask Pince for cat-care book visit Muggle bookstore
ask C. Weasley for advice cats not kneazles; kneazles v. interesting to C. Weasley; cats less so. So much for that.
Ask Filch for advice
Get something cats would like from kitchen - peppermint humbugs? tuna?
Put a watching charm over that alley in Hogsmeade - nothing to alarm cat though (ask Filch about this?)
Cat bed for greenhouse? or my rooms? both?
Oh Minerva, if you were here I would ask you. Of course if you were here I wouldn't be chasing stray cats all through Hogsmeade. And you would tell me not to be such a ninny, I'm sure of it. Hagrid's right: all tabbies look alike at twilight, anyway.
