Yes, it has been proven to be challenging.
I have tried Dr. Elseys pro-clean----they nibble on the Salmon.....and rabbit. --- I am currently mixing the 2 into the friskies. about 1/4 --- I see a decrease of the dry being eaten. makes me think they don't like it.
I have tried the Young--Zero---didn't work out.
the glycobalance was ok---However, the CHO is 25% ish. Not much better than friskies --29%
I am going to start covering the food at night. Maybe this will encourage only day eating....
Any suggestions would be appreciated from all. I also feed 4 ferals outside. So they will be transforming to what the indoor cats have..... any thoughts on the outdoor ferals will be gratefully appreciated.
