I'm sorry to say, but your ideas, while seemingly having good intentions, are misguided and will ultimately do much more harm than good.
I've worked with the local animal shelter for almost 8 years and nobody there would agree with what you are doing. I've worked with members of the SPCA and (unfortunately) PETA. PETA may agree with you, but they
are as nutty as the media portray them to be.

I understand you want to help, but trust me, it's not helping.
We have a few no kill shelters in the area. When they get full, they bring the overflow to us to euthanize them so they can say that they don't euthanize at their facility.
No kill shelters, while sounding good, simply don't work and most aren't run as intended from inception. When they become full, they either turn away animals or the animals are sent to us to do their "dirty work". They aren't magical places that can hold more and more adoptable animals until they can go to a suitable home. It's a eutopian idea with no basis in reality.
Sadly, we have to live in a reality. It's why shelters and other places are a very sad place to work 90% of the time, because we work in a reality and its limits on what we can do. Most of the volunteers we get quit very quickly after realizing this, and how many animals we have to euthanize.
In reality, you are causing the shelters and the public to work harder to maintain a realistic balance and your plan (while goodhearted) is not a good one.
I did ask an ACO and she said that you would be fined for doing what you are doing (at least in this municipality).
Sorry to be the voice of experience and reality.
