I've stopped the extra taurine. It wasn't making a difference, and Jennie got...weird on it. Grouchy. She actually went after me and tried to bite me one night, when I was brushing her, in bed. Our nightly ritual, which she loves. Sometimes I might get a little too...enthusiastic and she will let me know to go more softly, but not like this. I stopped the instant she told me to, but she actually came after me. I had to shove her away with the bed.
She also was getting very grouchy with Mazy cat and Queen Eva.
She still gets it with her prey model meals of course, but no more extras.
We're carrying on with the completely thawed meals (as opposed to partially frozen) and, I've added the pork bone broth, but I am not sure I will give it to her every day.
On the elimination trial front, since I've just run out of turkey breast (well I have more in the freezer but it isn't cut up yet) I am going to not use that this week and see what happens.
I am still dithering over the pork, whether to serve it raw or poached. She and Queen Eva are getting a small piece of cooked pork each day to get their bodies ready for it.
