This is totally coming from a non-breeder, but a couple of thoughts...
If someone is genuinely interested in the health / welfare of the cats and wants to breed more to produce quality "pets" (and break even or make a little money)...Then posting a link to something like "the cost of breeding" might be useful in all responses. I have read a few articles similar to that and they really opened my eyes to how much a litter normally costs to raise. This could scare off some of the ones that just want to make money...more so than lecturing them on "ethics"...It would also not come off as "snobbish"...just an "FYI" sort of thing.
