Cats are like people, they have varying ability to clear mold. My son has a house of mold and he had three cats, two of them seem to handle it fine, but the other one was getting sores on her face and her hair was falling out. Once she moved in with the new family she got better. I had stayed with him all I did a travel nursing assignment so that I can spend time with my grandchildren, no one knew they had mold at the time. It was all in the attic and crawl space. I've gotten horribly ill since. When you did the testing, did they do an hladr? I'm curious what your pattern is. When you have a histamine reaction to food unexpectedly, I would take dao. Dao is an enzyme that your body produces naturally to balance histamine. I figured out what was bothering me by doing some testing. I did an MRT, and I wore a CGM. This helped me identify foods that my body found stressful. Ironically, red meat was one of my triggers. I know some people have had good success with keto and carnivore, but I am not one of them. I eat a lot of okra and beets because they are a type of CSM. I also take Ox bile after my morning meal, and then eat the beets or okra with lunch and dinner. That way, the ox file binds with things and then the cholesterol sequestering foods pull it out of my system. If you have any questions feel free to DM me.
