The night ends with a hopeful development. Tasha started eating small amounts of dry cat food late this afternoon and –so far, so good– has kept it down! At this point I'll take any positive development as good news. I've also seen her at the water bowl. So at bed time (it's 11:15 PM EDT despite what the time stamp says) I can go to sleep with happier thoughts on my mind. Hoping tomorrow brings a cat gaining strength and getting healthier!
