In June of 2008 we wrote a story about our involvement with the monthly Spay/Neuter Clinic offered by the Alley Cat Angels Feral Cat Coalition at Angels of Assisi in Roanoke. The clinic was started in March of 2007 by Dr. Kelly Farrell, and on August 16, 2009, under the direction of Dr. Meghan Byrnes, the clinic “fixed” their 2000th cat!!
Here is a recap of the info we put into the original article explaining the protocol used at the clinic:
Feral cats are trapped in several southern Virginia counties by various groups and brought to the clinic early on Sunday morning. After arriving, the cats pass through several treatment stations before being returned to their cages for their return trip home. The first stop after Check-In is Anesthesia, where the cats are weighed, tagged, and anesthetized.
They then proceed to Ear-Tipping where they are given a thorough exterior examination, and a small piece of the left ear is removed to indicate to future trappers that this particular cat has already been “fixed”.
They then proceed to either Spay or Neuter Prep, based on whether they are female or male. Following the prep 
station, the actual sterilization surgery is performed, either by a team of volunteer veterinarians in the case of the females, or a team of veterinary technicians in the case of the males.Following their surgery, they move to the Medication station where their ears are cleaned, their eyes are medicated as required, and they are given medication for fleas, ticks, worms, etc. They are then moved to Recovery where they are kept warm and observed closely until they begin to recover from the anesthesia.
When they start to come around, they are returned to their cages (by matching a toe tag to a cage tag), and are moved to the Check-Out station for further recovery.
