This is amazing. I don’t know how these folks do this, considering the expense involved. They must have some serious benefactors behind them or a major Federal Grant.
UPDATE: Aha. I found it on their web site:
In January of 2007 the Catnippers team secured grant funding from PetSmart Charities, the Found Animals Foundation, Best Friends Animal Society and several private donors to launch the very first full-time spay-neuter clinic in Los Angeles dedicated primarily to serving feral cat caregivers and implementing TNR county-wide. Our new program is a separate 501(c)(3) organization, FixNation, Inc., which has been in operation since July 16, 2007.
