Hello, Yesterday, I did not know much about cats today after reading the Bible. Without thinking cat completely, I understand better their behavior and through this to ensure that humans and cats live at home almost perfect communion. This book is an indispensable tool for me which I refer very often. Given its very reasonable cost within the reach of all, it should be in the library but not on the bedside table every owner of a hairball. Sincerely Jacky C.
