What a difference 24 hours can make! I got almost 1 hour of sleep last night, but who cares?! I'm bouncing off the ceiling.
At about 12:35am, Maggie woke me up for the millionth time, so I thought I would try feeding her. She ate almost 2 syringes.

[Skipping over the twenty other things she did between 12:35 and 4:20.] At 4:33am, I had to get her off the TV which she had climbed up on!

At 5:12am, she was meowing at the door to go out and bop some boys.

Finally at 6:19am, we gave up and got up. Cleaned her eye, gave her an eye drop, and then 2.25 syinges. She NEVER eats more than 2 first thing in the morning! So, while taking Isabel her food, Maggie escapes the bedroom and procedes to push Tolstoy away from his bowl and eat his food!

Then she comes out into the kitchen and cleans out the bowl I mixed the food in.
Food done, adventuring begins! Next she climbs the back of a chair, jumps to the sofa, and chases James away. She then gets a drink, runs into Dante, and begins to bop him with both paws. He just sits there with this look on his face, "Ah, I'm being beaten up by a 4 lb cat. This can't be happening." He doesn't lift a paw in self-defense. She gives up and -- look, there's James again and he needs more bopping. A few good bops and then it's back up the back of the chair. Eventually, she runs out of plays to climb and fuzzpeople to bop so she heads back into the bedroom.
And look! Isabel hasn't eaten all her food!!!
Taking her off the clavamox may not have been the right thing to do when this is all over, but for right now, it seems like it was the correct decision. I can now stop worrying about her surviving and get back to worrying about her eye. And thanks to everyone for their thoughts and prayers. You may have helped bring about my Christmas miracle -- Piglet!!!
