It wasn't until I started reading this that I realised I had read the author's previous book "Tilly, the Ugliest Cat in the shelter". Like it's predecessor, this is a heart-warming tale of not just Toby, but of her other cats she had at the same time, namely Tilly of the previous book. Also, again, there is a lot of medical detail involving her husband, who tragically suffered dreadfully with double cancer, and of the author herself, a recovering cancer sufferer. Not for the squeamish in places.
