Betty Chu, a retired Chinese-American professor, is a bunny breeder. She is the proud owner of the world's furriest rabbit whose hair measures almost 38 cm long.

The 70-year-old has dedicated her last 34 years to producing prize-winning English angora rabbits. She lives with 50 of them at her home in San Jose, California, and is so dedicated that she hasn't holidayed with her husband since 1992.

Chu said she started to know Angora rabbits through a friend and she fell in love with them immediately at the first sight. Then she was determined to raise Angora rabbits.

Betty Chu, who is a member of the Northern California Angora Guild, competes at up to 50 shows a year. She is the undisputed queen of the angora category, with countless best-in-show awards to her name.

Angora rabbits produce angora wool, a soft fiber which is used to make clothing.
