I no longer live in Brooklyn, but this is a great cause. Discounted spay/neuter certificates. You buy the certificate from the site or various places in NY, then go to one of their 82 vets that accept the certificate and get your pet spayed/neutered!
It’s a surgery that people put off because of expense, so anything that makes it accessible is ok by me! there are enough dogs and cats in the shelter to go around and then some. We shouldn’t be adding to that.
