The Book of Neuteronomy

So we are supposed to get Prancis's balls chopped off soon, and our neighbors told us about the ASPCA's mobile spay/neuter truck. It so happens that it's going to be near us on Saturday, and we can save a couple hundred dollars by getting him neutered there instead of at the vet's.

I am a little hesitant because the program is intended to provide services to low income communities and they perform only a limited number of operations (25 animals a day) on a first come/first served basis. There is a nominal fee for people without proof of public assistance, but even with that we could be preventing someone from getting their pet fixed for whom going to the vet would not be an option. If we want to minimize our impact as gentrifiers in our neighborhood, isn't this exactly the kind of thing we should be avoiding? On the other hand, it would save us $300, which is a significant amount of money...but maybe that makes it that much more unethical?

I don't know, I'm not sure what we'll decide. We've also discussed the possibility that 25 people might not even show up by seven on what is going to be a drizzly Saturday morning on a holiday weekend, but that feels like a rationalization.
