Do you belong to Facebook groups who advocate for our vulnerable pets' welfare? I ditto the remarks on Craigslist browsers and people who skim for commodity-unwanted vulnerable pets.
Several rabbit Facebook groups have volunteers also connected with reputable rescue organizations. And as we know, tons of people get rabbits and are clueless about reproduction ages, so more rabbits are born adding to the 5.2K rabbits on Petfinder. Spay and neuter is essential - rescues will agree. Shelters who also spay/neuter are to be commended.
I am continually seeing posts for "rehome-needy" rabbits on Facebook groups.
