Mark Knight is one of the only behaviour specialists in New York City who concentrates on treating cat behaviour issues. His career in animal behaviour spans over seven years, successfully working with the most severely under-socialized cats. He currently serves as a client advisor for the national headquarters of the Amercian Society for the Prevention of Cruelty to Animals in New York City and is the only specialist referred to by many canine animal behaviour consultants.

Mark currently resides in New York with his two cats: 'Nana' a twelve year old rescued from the street as a kitten and 'Norman' a shelter rescue who had severe depression issues. Mark has also appeared on New York's 'CW11' Morning Show and Time Out New York magazine.

Mark is also a volunteer board member for AMP NYC (Animals Music Performances New York City); bridging musical events and artists with animal shelter rescue. He also enjoys writing and performing music as well.

Mark has developed several basic programs, each designed to achieve specific results. Although his approach is not a "one size fits all". Each treatment recommendation is a result of a thorough, individual evalution of the problem and circumstances.
