No Appetite!, (also was diagnosed with IBS/nutrient absorption problem) Options

[LittleGirl's...]

Writing to see if anyone has dealt with this, or has any ideas:

Recently, my friend's kitty was diagnosed with Irritable Bowel Syndrome (the type where the intestines have a hard time absorbing nutrients). She was prescribed a medicine for this but because it is in capsule form, it needs to be sprinkled on food---and she has almost no appetite.

For the appetite problem, she's tried:
1) Mertazapine but had a bad reaction to it
2) Vitamine B1 injection, and
3) steroid injection.
Nothing has worked.

She's had in-depth blood testing and everything else is normal.

Thanks for reading. Any ideas would be appreciated.
