I’m going to go against the grain a little bit, but please hear me out. 
I agree that some agencies’ restrictions are excessive, the organization I foster for included. Some of their policies are actually absurd:
-
No black cats can be adopted in October because of cults. This includes black-and-white cats with a greater proportion of black. First of all, I highly doubt there is a large enough number of cults in the area to warrant this restriction. Second, why would a cult member go through the elaborate process of adopting a cat from a rescue and fork over $100 or more when s/he could easily trap one outside or find someone who’s giving away black kittens?
-
If a pair of cats arrive at the shelter together, they almost always must be adopted out together. Even if one of them is a sweetheart and the other is difficult and will very likely decrease his buddy’s chances of being adopted.
-
You can’t adopt a kitten unless you have another cat at home or will adopt another cat. Their reason for this is that kittens need to burn off their naughty energy with another cat rather than on your furniture.
I do think a lot of this can be attributed to shelter workers not wanting to feel like they’re treating the animals irresponsibly, however minimal the chances are of something bad happening. I’ve only been volunteering with my particular organization for six months, but I could tell immediately that many of their policies were overreactions from something going horribly wrong once. If I had personally authorized an October adoption of a black cat to someone who ended up sacrificing the cat in some cult ceremony, I would likely be upset enough on a personal level to want to ban October adoptions forever. But I would hope that the organization would see past my personal reaction and make a decision that’s best for cats as a whole.
The problem is, organizations like these are made up of extremely dedicated people who love cats in general but tend to make decisions and policies based on cats in particular. They love cats and dedicate a lot of their time and energy to saving them, but they fall in love with Pumpkin and Smokey and Mr. Bubbles. And the importance of preventing anything bad from happening to Mr. Bubbles outweighs the importance of finding more homes for more cats.
I’ve found that restrictions are more numerous (and ridiculous) the more grassroots the organization is. The Animal Humane Society has you fill out an application and pay a fee, but that’s about it. They probably check in with your landlord if you’re a renter. My entirely volunteer-run organization has you fill out an application, have an interview with someone (which can be pretty grueling, depending on who that someone is), and if the interviewer has an off feeling about you for whatever reason, you’re out. One woman who screens potential adopters doesn’t let cats go to homes with small children. Ever. Thankfully, she realizes this is an idiosyncrasy of her own and recommends that such families talk to a different screener.
I don’t think restrictions like no-declaw, indoor-only, and especially required spay/neuter are excessive. I do think they are in the best interest of animals in general. You’ve probably heard this before, but declawing a cat is like chopping off a person’s fingers at the first knuckle. Not exactly humane. Letting a declawed cat roam around outside is definitely not humane, since he will defenselessly encounter bigger, stronger, clawed cats out there (not to mention dogs and wild animals). Even letting a clawed cat outside is questionable. I have mixed feelings about this myself, but I don’t let my own cats outside. The threat of other animals, vehicles, parasites and diseases is worse to me than putting up with a little whining at the door (and occasional escape attempts). And although I can’t get my cats’ consent on this, I’m fairly certain they’d prefer to continue their cozy lives inside my house rather than get hit by a car.
I very firmly believe that all household pets should be sterilized, and a shelter or rescue organization that disagrees would be grossly irresponsible. Why bother finding homes for stray and unwanted animals if you’re not, at the same time, addressing the root problem of overpopulation? I don’t know of any organizations that don’t advocate for sterilization, but I believe there are some that put that responsibility on the adopter, which is a bit naive. On the other hand, the Animal Humane Society spays and neuters their kittens at far too young an age (my mom adopted a kitten from them a while back, and they spayed her when she was 8-9 weeks old - they also didn’t make sure she was healthy first, but that’s another story). By waiting longer to sterilize a kitten, organizations like the one I volunteer for lose the interest of potential adopters who want kitties, but it’s better for the kitten’s health. It’s a tricky issue, but I can’t understand arguing against sterilization. Sure, everyone thinks her/his own animal is the model of the species and should be replicated, but seriously - there are plenty of other wonderful animals out there who need homes.
While I recognize that restrictions can drive potential adopters to buy kittens from pet stores (which is seriously the worst possible choice - please try a different shelter first or at a bare minimum find an add in the paper for free kittens), I still believe they are better than free-for-all adoptions.
I think the core of the issue may be the overall purpose one believes that fosters and rescues serve. I believe they should aim to find good, forever homes for all homeless pets. This includes trapping and rehabilitating strays, educating pet owners who are having trouble with their own pets (e.g., your cat peeing outside of the litter box might mean he has a medical problem - he’s not doing it to spite you), fighting against pet overpopulation through trap-neuter-release programs and discounted/free spay/neuter programs, and giving every animal a fair shot (behaviorally and medically) before euthanasia.
Wowzas. I’ve never written a post this long. I have a tendency to kill the few threads I participate in even with one or two lines, so hopefully there’s something here that has furthered the discussion.
