My adult cat has been vomiting bile on a regular basis for several months,
but not frequently. He will do it a few times in as many days and then
stop for a few weeks. Then the cycle repeats. My soon-to-be-ex-vet wasn't
concerned, said it was probably from a change in diet... even though it
doesn't seem to correllate with the change in diet, but I suppose it could
be related. Rudy is back on his old food, as I now keep him away from the
kitten food and he has absolutely no interest in the wet food--he just
licks it happily, and leaves it uneaten.
So the bile Rudy vomits is pure bile, no undigested food, no hair balls,
nothing else. He is overweight (currently weighs 12 lbs, should weigh 9
lbs). He is on a diet, but we're taking it slow. His fur is shiney, his
eyes are bright, and he is super affectionate. The only possible change is
that he seems to be sleeping a lot more than he did before, but I'm not
even sure about that.
Any ideas on what might be going on, if anything? I will of course be
asking our new vet about this once we get one, and I'll have a full blood
panel run even though he's only 3.

My cat does this prior to hacking a big hairball. I think the hair
makes him gag and vomit - and he is prone to soft blockages of hair in
the intestines. If your cat is otherwise healthy, I wouldn't be *too*
concerned, but keep an eye on it intake and output, and make sure to
give him hairball preventative if you can.

Since he *never* hacks up hairballs, maybe they are backing up in his
intestines? That would have never occurred to me. Thank you!

Hi -L., how's it going? Did your cat really bring up bile
before hurking a hairball? On a regular basis? How
dark was the green? or was it just mild lime-colour tainting of
regular vomit? I'm still trying to sort out how bad
a hairball obstruction can be and still end up puked
out, rather than causing a serious or surgical
obstruction.
TIA

Hi Lynne:
I don't know the answer to this question in absolute terms for
cats, but in humans I can tell you that regular occurence of
bile in vomit is a sign of bowel obstruction until proven
otherwise. The fact that it comes and goes suggests it
is not emergent total obstruction, but rather something
that might be occuring and recurring. I think you've taken
the appropriate steps in getting a new vet, that's for sure.
If there is some reason why this rule does not apply to
cats, I would very much like to hear back from you
(and your new vet) as to why that is. Bile should never
have reason to backflow into the stomach, there is
a pyloric sphincter there that should prevent it,
unless there are serious motility problems lower
down the tract.
Good luck, and hope the new vet comes through.

I'm thinking maybe hairballs in his intestines, after reading L's post.
And I will definitely bring this up with the new vet. Thanks!

Lynne - this hairball backing up happened to one of my cats years ago.
He kept losing weight and even the specialist didn't know what was
wrong. I let him out in the atrium and he started nibbling on a pine
tree and each day - for 13 days - barfed a hairball. After that, he
started eating normally and regained the weight. This was before the
hairball Temptations, etc.
Good luck!

Well weight loss certainly isn't a problem for Rudy! He's fatfatfat.
However, the pattern of his vomiting does suggest a partial blockage from
what others have posted, so we're going to start off with regular hairball
remedy (luckily he LOVES it). I haven't been giving it to him since he
never hacks up hairballs. It never occured to me they could be obstructing
his bowels! Hopefully this will help, but I will also consult with a new
vet and see what he recommends.
I really appreciate everyone's help with this. I hate to think of my
little king feeling as bad as he must when he is vomiting bile. I'm also
very pissed that my vet is even more incompetent than I could have
imagined... I feel a lot better about what was previously just a gut
feeling that I should see another vet.
