Leo had been acting a bit funny over the past few days - a little grouchier, a little more particular than usual. And a lot naughtier outside. We were concerned - a change in personality is one of the first indications that something is wrong. We had both taken to checking his lymph nodes every day - hoping to not feel anything, but expecting the worst. He had a checkup on Thursday (10/25). I was nervous - I did not want to have bad news.
