Debbie, I'm sorry to hear that CJ is still having problems - I wish I had a solution for you! I don't know about pumpkin, but I think yogurt is very good idea.

Sas, you mentioned Hills C/D. That is what I'm feeding Fister most of the time. On the bag is says: CD is a complete dietetic pet food for the reduction of Struvite stone occurrance in ctsIs has urine adicifying properties and contains a moderate level of Magnesium.

If I think Fister is getting a bit to "plush", I change to W/D for a while, it has less fat.

I hope you eventually find a cure for CJ!

Give him kisses and headbumpies from us!
