Just to update this in case anyone wanders in from a search. Jennie was diagnosed with cancer and I did not continue with the FMT, however, I had already stopped it before the diagnosis. I didn't care for the results I was seeing, upset tummy, even nausea, and once she had a weird episode that appeared neurological in nature. I did report it to AnimalBiome.
I should have asked them for my money back but I didn't think of it at the time, and they didn't offer a refund either.
Here is the report I sent:
About an hour after her fourth dose, which would have been 10 days after I started them, I was sitting on the couch and I had one cat on my lap and Jennie sleeping next to me. Jennie suddenly woke up and started batting at Queen Eva's tail, or so I thought.
It seemed a strange behavior for her but as I turned to look at her I realized she wasn't playing, she was having a spasm. Her paw just happened to be moving against the other cat's tail.
As I watched her entire body went into a spasm and she rolled over onto her back and her eyes were blank. I put my hand on her and she did not react, her body continued to stretch out and...shake.. for a few more seconds and then it stopped. This was before I knew she has cancer. It never happened again (that I know of) but I never gave her another pill after that.This treatment is heavily recommended in the IBD group, but I see a lot of posts both in the group and on the AnimalBiome page where the pet needs repeat courses of this to stay on track.
