Not surprised by this at all. “Animal trading” is such a touchy category within Meta. Once you get flagged for this, you can basically kiss your account goodbye. It is impossible to get support, even in cases like this where it clearly has nothing to do with animals. Meta simply will not touch it. There are other categories like this too. Ultimately it is easier/safer for Meta to just wholesale ban any use of terms even if it seems really stupid. This will only continue as Meta continues its exit from detailed ad targeting. Google is doing the same thing too.
