Cathcart & Winn is the longest established veterinary practice in Farnham & Aldershot. It was originally opened in the 1950's as part of the Fennell Veterinary Group.

In the late 60's the Cathcart brothers, Bob and Adair took over the Farnham and Aldershot Surgeries. Under their stewardship the Farnham surgery was relocated from Castle Street to its current site and became one of the first veterinary hospitals in the country.

Nick Winn qualified from Liverpool in 1981 and joined the practice in 1982. Five years later he became a partner and the name of the practice changed to Cathcart & Winn. During the 1990's Bob & Adair retired, leaving Nick as the sole principal.
