While pondering this I decided to bring him in next week unless there is a miraculous recovery and the good Doctor can take a closer look at his back half and we can talk more about those other things it could be: tumor (bad), neurological problem (usually idiopathic and hard to treat), or something else.
I do not have a good feeling about this. Jackson does seem low to me but then I seem a bit low to me so it is not easy to tell whether I am projecting or seeing a cat looking a little low.
So for now we wait. With puppy pads and towels and hopefully a comfortable enough place to sleep on top of me. And I give him another pill.
I am not sure how I will pay for Monday's visit but something will work out.
Through all of this his leaky heart valve, for which we have been giving him atenolol for years, has never given him any problems at all. Life is weird.
