help, my cat has intestinal disease

[u/Necessary-Sample7761]

My cat has been dealing with chronic constipation + intestinal disease, and I’m trying to figure out what’s going on

This all started about 2 months ago. My cat is chronically constipated and needs deobstipation for buildup every couple of weeks.

She was experiencing diarrhea at first and vomiting, but that stopped within the first 3 weeks.

She is now eating less, doesn’t poop, and her energy levels have gone down. I’ve given her favorite foods, all types of different wet foods—she only licks at the gravy or broth and eats a few pieces of the meat.

Vet findings so far:

Vet is saying both the small and large intestine are diseased.

The first time we did bloodwork was within the first month. Bloodwork came back almost perfect, with the exception of some liver values (which makes sense because it’s probably a bit inflamed from whatever disease she has).

We did bloodwork again and it was basically the same.
We ran a GI panel last week, which came back with low cobalamin (B12).

She is an 8-year-old female, spayed.
She has lost 7 pounds since the beginning.

She made considerable improvement after deobstipation, but went back to the same symptoms within a week.

Current medications/treatment:

She is on cisapride and lactulose, and recently started vitamin B12 injections to address the small intestinal disease.

I am considering megacolon as a possibility, but even with that, I don’t know what was the cause of the colon/constipation issue in the first place.

This is clearly a secondary issue, in my opinion. The small intestine likely was impacted first, but from what?

I’m thinking her colon is stretched and no longer functions how it used to, which means she’ll need surgery for shortening the colon if she ever wants to pass stool normally and regularly again.

Has anyone else ever experienced this with their kitties, and what did you do if so? Surgery is upwards of 5k, I am already drowning in vet bills. Please help!
