Spaying and neutering is important, and here's why

I have come to the realization that I will not be able to save six kittens. Five of them are feral and only one is even eligible to being saved, and it's a very very painful to realize that even he might be able to make it. Tomorrow I will take them down to Pinellas County Animal Services, which has a good track record of adopting out animals, not immediately putting them down in 72 hours, and has space for them. The only issue is that they will have to go through a behavior assessment, and seeing as five of them are almost completely feral(except around me and even that's iffy), I can only hope that the one that's the most confident and friendly will be able to pass it. Obviously it would be miraculous if all six of them passed, but realistically I can't expect more than two to pass it.
The only good part I can see of this, is at least if they're put down, they will not suffer if they were released to fend for themselves. Nor will they repeatedly reproduce, thanks to Florida's warm weather, and procreate more unwanted litters. They will also avoid the potential of being cruelly mistreated by people or suffer a horrible death because of them.
I'm terribly heartbroken by this, I've spent the whole day calling rescues, shelters, sanctuaries, feed stores, and veteranary offices trying to place just the one, but to no avail. And it's with a heavy heart that I'm taking them to Pinellas County Animal Services. My only regret is not trying harder to socialize, take care of, and find a place for them.
The worst part about this, is that it feels like I'm the only person willing to bear some of the responsibility of this situation or gives two shits about them.
That being said, I've decided that if I ever run across another pregnant dog or cat, I will try my damnedest to have her spayed, so that I can be spared the heartache and hassle of dealing with another unwanted litter, when every year there are so many homeless and unwanted cats, dogs, kittens, and puppies. The only reason why I can see why anyone should let them have babies is if they're too far along to be fixed at that moment.

With that being said, please please please, spay and neuter your pets, if only so you don't have to deal with I have these past four weeks.
