The new owners pay for the shots, neutering/spaying -- which can run as much as $300 depending on the clinic. When the economy was better, Emancipet would come and neuter/spay for free. I did it for awhile (the clinic gave me a discount) but am too broke to continue. I am just grateful they have homes so that we do not have to pick their little bodies up off the road. I live near a major thoroughfare. :(
