I'm also ok with humor at my own expense, I think it comes with age.
Definitely I've spent time looking at the feeder on your site and others, very close to buying but when I watch my live cam positioned by my feeders, all day long I see nothing. The feeders/set up I have, there is no spill but to your point, yes a rat could get up there and enjoy. And the moment I see that, I will go with your feeder. The cats I will always adopt, it's such a win/win. Barn cats that don't want to interact with humans are the least wanted. So I have 3 at a time, different parts of my property, I enjoy that I'm providing a much needed home and they are earning their keep for sure. I don't exactly understand why it keeps rats away as I have seen them eat mice, but not rats. They don't really "kill," rats. But it's working..... One cat lives in a house attached to my coop, another in a house by the truck and hot tub and another seems to like hunting the River bank. I live on River frontage and I know there are rats living in the bank.
I have seen this. There is a particular time of year, maybe spring? Where my dog has alerted me to areas like the wood shed and under stairs. But then nothing. I think they consider places and then decide it's not safe. Just like has been stated above, I've been diligent about removing anything that would provide a quick easy place to hide (moved the woodshed too.)
Thanks for the education, it's really helped me, sincerely.
