Purebreds can only come from a breeder: it doesn't matter if they have perfect conformation to be a "breed", they need papers before they're considered pedigreed or purebred. These guys are standard breed longhairs, or DLH's. And they're GORGEOUS!
Unfortunately, it can take 6-12 months to get a cat admitted to a rescue. It's not that we don't want to and it's not as though breed makes any difference (although I'm speaking for my rescue only, since it's the only one I work for!) it's that we get about 60 calls a day and we adopt out about 1-4 cats a day, if that. We know that the vast majority of people who call us are just trying to do the right thing by the animals, which is why we offer free S/N and vaccinations/deworming/defleaing, but we simply can't home them all, as much as we would LOVE a world in which we could do that
if you can get the unneutered one neutered and feed them until you find space in a rescue somewhere, that would be great. I'd also work to get the cats to a point where you can handle them/touch them and give them kisses
