Draven you may not have known, seven years ago, when you were going to have children. However, seven years ago you had to have known that cats live 12 or 14 or 16 years ... or sometimes even longer than that. You made the choice then to get these cats.
It's devastating, the number of unwanted animals out there, the number of cats and dogs that are euthanized every day because no one wants them. Some of them were never wanted, not a day in their lives, but exist solely because some idiot decided not to spay or neuter his pets. Others were once loved and wanted until their owners changed their minds. It bothers people. It saddens people to know how many animals die needlessly because humans created this widespread problem of unwanted dogs and cats. That's where the criticism comes from.
Also, there are people on Toledo Talk who have recently or maybe not so recently lost their beloved animals, and who probably would've made almost any bargain to keep them alive and healthy. You know? 'Take my arm, my leg, my house, my car, take every last cent I have in the bank -- if only my pet will be OK.' Then someone comes along with two healthy animals he doesn't want anymore. Like they are a sofa that doesn't match his living room's decor anymore. That, too, is bothersome. It might even be borderline offensive.
So you feel criticized. So what. How are your cats going to feel when everything they know, when the safety and security and stability of the home they've had for seven years, and the people in it, and even possibly each other, are taken away from them? How are they going to feel in the back room of an animal shelter when they take their last breath on a cold table at the hands of a stranger?
You came here for "help" in shirking your responsibilities and adding to an already huge problem, is the way I see it. Excuse a few people for not wanting to smile sweetly and offer you that help.
Ultimately, if you DO decide to go ahead and re-home your cats, I sincerely hope you find a loving home for them -- together. Not because it'll make life easier for you or because it'll solve your "problem," but because they deserve it.
