sick kitty

On New Years Eve boyfriend called me at work to tell me Mr. Bojangles was sick.
It was difficult assessing the situation while away from home. So I asked boyfriend to make kitty comfortable and let him rest.
When I got home from work Mr. Bojangles didn't greet me per his usual. He was under the coffee
table just as he had been when I left that morning for work.
I layed on the floor with my upper body under the coffee table. I wanted to have a look and see how he was doing. I spoke to him. His only response was twitching to the tip of his tail.
I pulled him out from under the table to have a closer look. As I pulled him he cried, meowed/screamed out in pain. 
I believed he was probably dying.
We wrapped him up, boyfriend and I, and took him to the animal hospital emergency room.
They examined every inch of his body looking for bite marks from another animal, or an injury of any kind.....................and they applied pressure to his bladder forcing urine out making sure he didn't have a blockage. Urine squirted out...........and no injury was to be found.
 They prescribed an antibiotic for a possible systemic infection, thinking that maybe he had been bitten by another animal, and gave instructions to return if his condition worsened.
Yesterday while at work, boyfriend called several times throughout the day and evening with updates on Mr. Bojangles condition. "He's still sleeping. He just lays there and sleeps."
After a tortuous day of working but thinking all the time about my kitty, and wanting just to be there for him......the work day and night was finally over.
Kitty was in my bed when I got home.
I laid my head next to his body and told him I loved him. I petted him. He looked me in the eye and I pleaded with him not to die.
Boyfriend and I discussed taking him back to the emergency room for i.v. hydration. He wasn't eating or drinking.
I brought to him an ice cube. He licked it and then made his way off the bed when he saw We-Ping walk past the bedroom door. He didn't chase after him like he usually would do....but still, he actually stood AND walked..... he went to the kitchen and lapped the water in his bowl for what seemed like forever.......and then he went under the buffet to sleep.
I laid on the couch to be close to him.  Soon there after he was standing on, and then laying on top of me. I petted him until we both drifted off to sleep.
When I woke this morning he was stretched out on his back against my body........and he was breathing. I tried to get off the couch without disturbing him........but I woke him instead. He lead the way up the hallway to the bathroom and for just a second  he did his little "I'm happy/life's good" dance that he does.
It gave me a lot of hope that he will be okay. Maybe he does have an infection and the antibiotic is doing it's job.
There's a ray of sun light shining through the dining room window on to the dining room floor. It's where he's resting right now.......

I've worked 40 hours the past three days.
So today I plan on sitting around doing much of nothing, and loving on kitty
