I picked up a number of books from the library to try to address the issue of my spraying male. This book had very little information in that regard but helpful information in other areas. The primary piece of information for me was a nutritional breakdown of the ideal diet. My cat has minor crystallization in his urine and the vet is recommending a diet change. The nutritional breakdown is helpful for when we go to the store this week to select his new diet.
