Biography
Wolsey the cat was described as a large tomcat with tabby markings. He was a capable hunter, and utterly disdainful of human beings. He originally belonged to Joan Redfern. She gave Wolsey to the Doctor to 'guard' him. (NA: Human Nature)

Wolsey was made into a 'person' when a Perfecton missile hit the ship on which he and owner Bernice Summerfield were travelling. In the Perfecton-generated reality, Wolsey appeared as a seven-foot-tall, fully-clothed cat with a large cavalier hat. (BNA/BFBS: Oh No It Isn't!)

Wolsey was present when Peter Summerfield said his first word. (BFBS: The Mirror Effect)

As Wolsey got older, he became lame in his back leg. (BFBS: A Life Worth Living)

Though Wolsey was neutered, he nevertheless managed to sire several litters of kittens during his time at the Braxiatel Collection. Wolsey died in January 2606, at a very advanced age, and was buried on KS-159, in the gardens of the Braxiatel Collection. (BFBS: Something Changed)
