Thank you for the advice, and I do feel better hearing of others and their struggle with the feral cat. Avajoy, your cat sounds just like Minnie. No aggression, just the freeze and burrow. I will try the reading aloud, and less forced interaction. I will have to find her special treat. Tuna doesn't seem to do it like it does with the others. Maybe she was just too scared then.

I will keep you guys posted, and thanks again.
