K & L
I agree with you completely, they have no way of knowing, I don't blame them at all for the rule about spaying/neutering. but I do blame them for the killing of the kittens, and i think it can be easily figured out if a cat is pregnant?

I feel so bad for Cassie, that they did that to her babies.
I would have taken them too if they had told me she was pregnant, I guess they thought I might back out..who knows.
thats the (in)humane society for you!
