This book brought a lot of smiles and laughs of recognition. As the "pets" of 2 homebound felines, we gained a world of understanding about how our companions viewed us and our shared home. The startle-can trick works wonders for keeping cats off furniture, even when we "alpha-cats" are not around. Handy habit-troubleshooting guide and clear explanations of what underlies the behavior. Have already shared the book with other cat-companions and they are getting their own copies for continued future reference.
