Jeeves has returned from the hospital! He has a very long incision, neatly stapled, and a shaved portion on his hindquarters to which the vets have affixed a clear patch that releases pain killers, (we were given explicit instructions not to eat the patch). In addition to those instructions, we were given a veritable pharmacy of pain killers, antibiotics, and healing agents for his stomach. This is in addition to all the eye medicine he is still on for the black eye he mysteriously came home with a few weeks ago.
He is in good spirits (almost too good - he celebrated getting home by jumping back and forth over the back seat of the car) and, aside from the heat (it's in the 90s F today), he seems content to be home.
The offending object was identified as a squash stem along with various bits of vegetation. We are still unsure as to where he found a squash stem this time of year, especially considering that he was under quasi-house arrest due to the black eye!
His prognosis for a full recovery is excellent, given his physical condition, age and stubborn nature. We are glad that the worst part is over!
