You’re already asking good questions, which means you’re doing a lot better than many of the people who adopt without thinking. You’re also looking for an adult cat, which means you aren’t going to have to deal with a kitten’s destructive exploratory phase (although, fair warning, adult cats can still be destructive if you don’t prepare properly).
One thing I would say is that you should consider two versus one cats. Some cats don’t handle being alone for a long time well and can become unhappy, while others prefer not having feline company and would be just fine alone for ~48 hours. A good shelter or adoption agency may be able to tell you whether a cat prefers company or solitary.
Like some other commenters, I would strongly suggest going to local shelters and discussing with them. They should entirely understand if you aren’t able to adopt immediately and be able to discuss particulars with you.
This. Actually launching a community is hard. Launching a decentralized network of communities is damn hard.
I’ve been around for long enough to remember the internet before megasites like Reddit, when every community had their own forums and/or website. Specific mod for a specific game? Unique forum. Specific sub-community of a fandom, like a bunch of tech nerds analyzing the starships in Star Wars? Unique forum.
And like, I don’t deny that losing that hurt. Each site had its own unique little flavor of community, and the great centralization of the internet definitely steamrolled that flat in favor of mainstream appeal. But centralizing did also improve ease of discovery and access. Now we’re trying to build all of those little communities back in what - 2-3 years? In comparison to the 10+ they had to grow in before? It’s not going to be easy.
