Helen Perley was the proprietor of the White Animal Farm, established in 1934, on Seavey's Landing Road. She was a self-taught woman who raised and bred mice and rats that were shipped all over the world. Research facilities used her rodents because of their health and purity.

Besides the mice and rats she also had gerbils, hamsters, birds, reptiles, and a variety of wildlife. She was known as a healer of animals and also a teacher.

People brought injured birds and animals to her for help.

Helen Perley gave tours of her farm and nature walks in the woods nearby. She also took animals to schools and nursing homes. During the 1950s and until the mid 1960s she was also a popular attraction at Old Orchard Beach.

She died in 1994 at age 90.
