Aren't there enough dogs and cats to be adopted from either a rescue, SPCA, Humane Society or people for one reason or another can't keep theirs!?
You charge a "rehoming" fee for what we use to call "Heinz 57" and give them a "designer name."
You either aren't responsible enough to have your animal spayed or neutered or you just don't care and collect your "rehoming" fee."
What most of you are doing is actually "selling" these animals. Just a way to get around Craigslist TOS.
Some of these puppies and kittens will end up with either a loving home (if they're lucky), running feral, picked up by a shelter (and POSSIBLY with a new family) or dead.
How pathetic.......and all they want to do is be loved and love you unconditionally.
