I was confused because we went from "i think there's a dog shitting in my yard," to trapping a cat days later, to learning that you had been surveilling and documenting said cat for months.

I'm allergic to cats too. I used to be pretty bad when I was younger... eyes swelling shut, throat closing up. But it doesn't sounds nearly as bad as yours. Mine isn't as severe these days but I do have empathy/sympathy for the phyiscal reactions.
