Welcome on yiffit!
You don't need to have a fursuit, fursona, go to cons or anything else to consider yourself a furry. If you enjoy furry content, or intelligent animals in general, that's more than enough. And even then, you are free do define you as one or not.
I'll swing around Pokeyiff sometime~
Rescue organisations normally know best, since they do handle a lot of cases like these on a daily basis. <1 month is really young, poor thing. Since the, can't eat real food yet, some milk and a cozy blanket will do good. Or wven one of those hoodies with big front pockets. Definitely keep the fur tidy, that is usually the best indication (though I am not even sure on this low are to be honest). Thank you for helping it out. At this age it very much is helpless, on its own yet. The 6 months old is probably fine, as long as it's fur is shimmering. Maybe put out some wet food with stuff helping with worms for now.
Well, I know what I get to post, then :>
