Yet another cat sub. Cats that beep and silent meowers.
And, just for giggles, started r/beepercats first but didn’t really like the name.
Thanks!

Thanks to u\SurpriseFurMama here in "Born yesterday..... He's going to be joining my fur family in 8 weeks time.". It is not in either wiki (https://www.reddit.com/r/Catsubs/wiki/index/ and https://www.reddit.com/r/suballthecats/wiki/index/), or u\Caratteraccio's "other 200 subs to add" thread (though r/suballthecat now includes all of the subs listed in that thread).
In the quest of "oh, another cat sub" and trying to collect them into one place and see which ones are actually worth subscribing to, I've built a script that does the data collection and wiki updates.
So, go to the wiki and browse. They're also (minimally) tagged in the data page.
If I'm missing some, create a post with the link to the subreddit and suggested tags.
Not all all the cat subs are there. I've pruned quite a few that are inactive and have less than a dozen posts or have any sort of spam on the front page.
Remember, it's in the wiki.
