The record is held by a Burmese cat called Tarawood Antigone, who was just four years old at the time. She gave birth to the entanglement of kittens on August 7, 1970, in her owner’s home in Oxfordshire, UK. Of the fifteen kittens that survived birth, just one of them was female! Over her lifetime, a cat called Dusty had a total of 420 kittens.
