Thank you Pookie!
If bone broth is the answer for Mazy cat, it explains why she (and I) had to go through that whole mouth thing. I turned to bone broth in desperation. Today is one week she's been having it daily. she is just going to 1/3 raw and 2/3 canned (going back to raw slowly)
I was going to drop the bone broth to only two or three times a week, but I may have to suck up the inconvenience and give it to her daily, forever, if this is what it takes. I just hope she'll like the chicken version as well as she likes the Cornish hen. I really really can't sacrifice any more of her hens to it.
On the other hand a Coleman (certified organic, non-GMO project verified) chicken will make a lot more broth so i won't have to make it as often.
Where to put it will be an issue. Is always the issue.
