Flower woke me up this morning: a good sign as this is something she has always tended to do with me. I woke up and offered her a very small amount of no-salt-added tuna in plenty of its own water, which she did not eat or drink but only tasted. She did eat some cat treats: the kind from Grandma Mary and some that Ashley just got yesterday. I offered her some of the A/D food several times through the day, warming it up and not warming it up, which she did not eat. She ate some more treats again later from Ashley. We went to the store to get a couple toys for her to try to get her active a little bit and also picked up another kind of food that Ashley recommended. Flower only ate the "gravy" from the food and did not eat any of the solid portion. Also, this evening, after checking her water in the kitchen, I found that she has not had any of it to drink in the past 24 hours. I changed the bowl to a ceramic one, refilled the water with bottled water, and placed a couple small pieces of her dry food in the water in order to facilitate her depth perception. I also replaced her dry food (which I saturated with water), and provided some Pedialyte for her to drink in the living room (also with a couple pieces of dry food added). She began this morning more active than before and last night I scooped a lot of urine out of her litter box, but as the day has progressed, she has become more sedentary. Tomorrow I will administer sub-q fluids in the morning and try giving her a dose of Valium to stimulate her appetite, as well as continue her course of amoxicillin. I go back and forth between being worried and hopeful, but ultimately, Flower simply seems depressed. I don't know how else to characterize her behavior.
Another thought: I offered her food this morning and then, even though she hadn't eaten, I went ahead with her amoxicillin dose. It's possible that this might have upset her stomache in such a way that she didn't feel well for most of the morning or afternoon.
Final comment: I have left a veritable smörgåsbord out for Flower and just now she got up off of the couch to take a look around. She passed by some tuna-water and the Pedialyte I decided to try but she did go for some of the food that Ashley got this afternoon. It appears that she mostly licked off the remaining gravy and I cannot tell whether she actually ate much of the food or not.
