If you're just joining fediverse welcome to Mastodon. Cat is not happy about all this work even on caturday. Why?
I had to mute over 200 posts in the last 30 minutes or so. Cleaning up the feeds so you can get to a few good posts will take lots of effort because there's no algorithm
You'll notice many posts come from sources like dlvr ... review them and use filter/block
When the live feeds gets too messy and too much to handle, have to use tags instead like this at the end of the url
/tags/pets or /tags/sea or /tags/photo
