Oh no! I was so hoping she would take to a new diet easily. I certainly hope you can find something she'll like. Have you tried making your own food for her perhaps using real boiled or roasted chicken? I know there are actually home recipes for pets you can find on the internet. Maybe your holistic vet will have some ideas.
I'm sorry she hasn't recovered from the ultrasound! Hopefully there is no next time, but the vet I went to for Phinehas was great and no shaving or relaxants were necessary! I sat in the room and watched while it was done. It was still stressful for him, but painless

Many healing vibes for you and Mitzi
