Here's a very related question but seems to be about clay litter: Flushed cat litter, maybe clogged?
I flushed paper cat litter down my toilet. I have been doing this for 5 years without any problems, but I wasn't paying attention and flushed way too much at once, so it clogged.
Plunger did nothing. Also tried Green Gobbler with boiling water, 2 overnight attempts, did nothing. I got a 6 ft auger, and it met resistance about 5 ft down. I was able to break through it, but the toilet still won't flush, so the 6 ft auger is just a little too short.
I was able to pull some of the litter out with the auger. But I'm a little unclear on how the auger is supposed to work. It seems that for a larger item, it's supposed to catch on so you can pull it back up and out of the toilet. But for paper litter, would I just have to pull a small amount out each time, or can it just break it apart?
I was thinking of trying a 50 ft auger next, but my main concern is that it will just push the clog deeper and it will get even more difficult to clear. Or does the pipe get larger when it gets pushed deeper, so that isn't a concern? I'm on a house with a septic. The shower and sink in the same bathroom are not clogged.
Picture of the litter. It is small pieces of compacted paper
