Been there, done that, and it's a disgusting problem. Best solution for
me was to take the offending kitty to a groomer/vet for a "baboon cut"
(also some call it a "potty trail cut" or "sanitary shave". They shave
the butt area, and down the back of the legs. No more dingleberries,
ever!  IIRC the vet charged about $25 for this, and it would last about
4 months. I didn't mind the $25--there are some things that it's just
better to pay the professionals to do. Good luck.

I usually take my long haired kitty to the vet and have her nether regions
trimmed.  Sure, it looks funny - but after they get over the *shock* of
getting /that/ area "invaded", she doesn't mind - probably appreciates it as
a matter of face :D

And as to them ingesting their own feces - how do you think they clean their
butt?  They use their tongues - and they ingest some in the process.  Been
doing it for eons (long before man domesticated any cat) - and doesn't make
them "sick".

So the housing people did not make you get rid of a cat? That's
great.

When we got our cat Boo she was very fat and could not reach to clean
herself, so we had the same problem. It is very simple. Get someone to help
you.
They--or you--wrap kitty in a thick towel and hold him in such a way that he
cannot bite or scratch, and his butt is uncovered. Use one of those
haircutting
kits you can find at Walmart or whereever--the shaver looks like an electric
razor, kind of? Shave the area that has poop stuck to it.

Don't say you CAN'T do it. You CAN. I did, so I know. And yes, Boo
was wild and scratched and bit.

I have exactly the same problem with my 6 year old girl who is very
longhaired.  I've only had her for about 8 months, and she won't tolerate
being held.  I can pet her all over, get her to roll over on her belly, but
she freaks when I get near her ah.  I cannot hold her for long, even on my
lap.  Also, she doesn't like to be brushed very much and always runs (well,
walks fast, shes fat and slow) from the shed ender.

When I first got her she came with a basic brush, which she will tolerate,
and even likes around her face. Then I got the shed ender, because she was
having a lot of hairballs.  I filled bags and bags full of hair in about 2
weeks of combing her every day.  Now she gets pissy and hisses at me when I
go to use it on her.  Fortunately she has no claws.  Probably associated to
why she's not too fond of being handled.

Anyway, I've tried giving her treats while trying to comb her or clean up
her behind, but that worked for about two minutes.  I was very surprised
about that because she lives to eat.  I don't groom her as often as I should
because she hates it so much.

OK, now that I posted my long post, I see the solution to my problem was
already written about in the thread.  Duh, why didn't I think of that.  My
first cat.
