It'll be sometime next week before we have the results of the biopsy, but Butch is home.
Much to everybody's relief, he had no problems during anesthesia this time. He is showing some of the same behaviors that scared me so much after his last bout of anesthesia -- whining with every exhaled breath, pacing, bumping into things -- but it doesn't frighten me as much this time around.
I can tell that the biggest problem we're going to have in the next few days is to keep him from "chewing" on his freshly shaved behind and possibly pulling out stitches. I just fussed at him twice to make him stop it. After the second time, he climbed off the futon and went into the living room. I followed him in there and found him -- no surprise -- with his head up under his tail.
So, since Butch can't be trusted, I won't write as much as I intended to tonight. I'll post again as soon as I don't have to police him. In the meantime, please know how much I appreciate your concern and your prayers.
