On every page, the Cat Trivia calendar tells you something new about the cats you love and though you knew. The Purr-sonality Guide: Meet the Egyptian Mau, a breed that will trill, chirp, wag its tail, and make biscuits (that is, knead with its paws) to express happiness. Famous Cats: Towser the Mouser, who holds the Guinness World Record for killing the most mice over her lifetime (estimated to be around 29,000). Plus, Travel Locations for Cat Lovers, Meow-nificent Movies, owner tips, cat lover quotes, and surprising (and maybe not-so-surprising) facts: A cat typically spends 30 to 50 percent of its day grooming itself.​
