kb2yjk: Glad to hear she is eating again!

I found the following on a site that talks about high-fibre diets...and describes some of the negative effects as well:

Rations high in dietary fibre produce the following effects :

On the intestine itself

1. Increased small intestine wall thickness (mucosa)
2. Increased small intestine weight
3. Changes in the villi :
o Increased number of neutrophils
o Increase mitosis (cell division rate)
o Increased number of crypt cells
o Blunting and disarray of villi (soluble fibre)
4. Thinning of colon wall

This is just one site...I am sure your vets will have other info also.
