Simi Valley Spay and Neuter Clinic


It has been a great ride helping so many and we continue to grow and assist more. SInce the stand-alone facility opened in 2009, we have completed over 64,000 spay/neuter procedures on cats and dogs. In addition to our main undertaking which is spay/neuter, our staff will go the extra mile by providing humane medical treatment to animals in need so they can live a healthier life. 

I know I tell you all the time but the resolve, enthusiasm and complete love of animals by all of the employees and volunteers is incredible to see and dear to my heart.
