Does ANYONE know - with Chronic hairball vomiting, are there ANY diagnoses possible other than IBD o

I am really frustrated and sad...when I search for answers for this, "other GI disease" is sometimes mentioned but nothing specific.  Help much appreciated.

If what is vomited is always hairballs, then improvement in feeding and grooming should solve it.  If the vomiting is NOT always hairballs, that is a different matter.  You have not given enough history and information for us to even speculate at this point.  Howold is your cat?  How long has this been going on?  How often is the vomiting? Are there always hairballs in it,or  does she vomit food or clear foamy liquid?  What do you feed her?  Is she longhair or shorthair?  How often do you groom her and does a lot of hair come out when you do?

Red Top Rescue:  Thank you for  your interest.  I have provided this information ,but in previous posts.  Here is a brief summary:

Obi is 15, domestic short haired, neutered.  Healthy all his life, but definitely a hairball vomiter, which increased dramatically at the end of winter, to almost every day.  Initially it was thought that he was over grooming and that was due to a food allergy, so I changed his food several times.  He is now on Nature's Variety Rabbit, a novel protein, and with a lower fat content than other formulas in that line.  He loves it.

It is pretty much ONLY hairballs.  Once in a while there is a small amount of food in it but mostly it has the appearance of stool, in fact, sometimes I think it is, but it is not.   I brush him daily with a Furminator.  Sometimes I can brush out gobs of hair and sometimes not.

Obi was recently worked up.  Chem panel was normal.  TAMU done and revealed mild inflammation of the pancreas, but normal functioning.  B12 was low, and he was started on B12 injections last week even before the Tamu came back.

He has been on reglan, pepcid and pred (and some supplements which I  stopped, egg yolk lecithin and slippery elm bark syrup).  It probably would not hurt to re-try the EYL, but I dont want to start the SLB syrup, because it can intefere with absorbtion, and right now Obi needs his pred.  That was bumped up from 2.5 to 5 two days ago.  He was feeling poorly for several days, but now I would say his mood is very good.  And, he has a great appetite and has not lost any weight.

I t hink that covers it.  The vets say small intestine disease, and because of his age, they speculate lymphoma.  Or IBD.                  

It is most likely IBD. Did ultrasound see thickening of the intestines? The low B-12 is a major, major red flag for IBD. Pancreatitis also often accompanies IBD. I thought I'd posted a link to this article before, but just in case:

Whether IBD or diarrhea is dependent on where the inflammation is localized. IBD causes motility problems, period. For treatment, the basic principles are the sane, whether diarrhea or vomiting (or hairballs):

My Tuxie has had a very, very, very bad time with hairballs this year. I give 1/4 egg yolk every-other-day, 1 full capsule of egg yolk lecithin 2x a day. That normally does it. Not this year. So I added a full tablet of Vet's Best Hairball relief tablets 2x a day. That helped. Then they came back with a vengeance. I then used 2-3 CC globs of vaseline (in addition to everything else). That got a lodged hairball moving. Then i stopped the vaseline. Then he was puking bile every morning, sometimes with some small amount of digested food. So I made slippery elm bark syrup (1 teaspoon per cup of water, stirred and simmered for 5 minutes). I added this yesterday. No hairball, no vomit, no bile this morning.

You can absolutely give slippery elm when a cat is taking medication. You just need to give it at least 2 hours on either side of meds.

Is he on an all canned, grain-free, high protein, low-carb diet?

Oh sorry, you addressed that.

Is it safe to give two hours out if the cat has had a flare up of mild pancreatitis?

I know of no reason why slippery elm bark powder would be contra-indicated for pancreatitis. @GoHolistic?
