"Memory" is the standout hit song from Cats. By 2002, the song had been played over two million times on radio and television stations in the US.[99] It was the most requested song at piano bars and lounges in the 1980s, and was an equally popular choice at weddings, concerts and other gatherings. As of 2006, the song had been recorded around 600 times by artists such as Barbra Streisand, Barry Manilow, Judy Collins, and Johnny Mathis, in covers ranging from easy listening to techno.[334] According to Sternfeld, it is "by some estimations the most successful song ever from a musical."[318]

Among domestic cats, males are more likely to fight than females.[149] Among feral cats, the most common reason for cat fighting is competition between two males to mate with a female. In such cases, most fights are won by the heavier male.[150] Another common reason for fighting in domestic cats is the difficulty of establishing territories within a small home.[149] Female cats also fight over territory or to defend their kittens. Neutering will decrease or eliminate this behavior in many cases, suggesting that the behavior is linked to sex hormones.[151]


The cat (Felis catus) is a small carnivorous mammal.[1][2] It is the only domesticated species in the family Felidae and often referred to as the domestic cat to distinguish it from wild members of the family.[4] The cat is either a house cat or a farm cat, which are pets, or a feral cat, which ranges freely and avoids human contact.[5] A house cat is valued by humans for companionship and for its ability to hunt rodents. About 60 cat breeds are recognized by various cat registries.[6]
