Pre-Owned How to Toilet-Train Your Cat: 21 Days to a Litter-Free Home (Paperback 9780894808289) by Paul Kunkel

Last year Americans spent $400 million on 1.8 million tons of cat litter--enough to fill the Empire State Building two and a half times! Now, Paul Kunkel presents a foolproof, 21-Day Program for teaching any litter-trained cat between the ages of six months and ten years to use a toilet instead of a litterbox. Illustrations. Paul Kunkel, who toilet-trained his first cat while in college and who has continued to train his own and his friends' cats ever since, presents a foolproof, 21-Day-Program for teaching any litter-trained cat between the ages of 6 months and 10 years to use a toilet instead of a litter box. (Older cats can still be trained, but the process will probably take longer.) Requiring nothing more than magazines and/or newspapers, masking tape, heavy-duty plastic wrap, and a supply of fresh litter, the plan begins with you placing the box next to the toilet and, after gradually raising it to the height of the seat, ends with the cat--well, using it like any other member of the family. For life.
Along the way, concerned owners learn why toilet-trained cats may be happier and healthier cats. In well-researched, fact-filled text, Kunkel traces the history and behavior of this barely domesticated animal and proves why the box is bad for cats; why many cats equate the smell of a litter box with danger; and why the fragrances, deodorants, dyes, and disinfectants found in most litters are detrimental to your pet's well-being.
