Annoyed!

We still have 4 kittens and the stray Mommy Cat living in our backyard. We took a kitten, and someone else took one. I have postered, placed ads on the internet and the paper. Handled all the emails and all the calls. The cats have to go to a shelter next week, if they don't have homes. Do, I like it? No. But, the kittens are starting to wander and will soon be hit by a car or eaten by a racoon. The mother will soon be pregnant if she is not already. If they populate more in our yard, we will get in trouble with the health board. So, why in spite of all this, is DW making me feel like the bad guy. She is sulking and saying I don't care and haven't done enough for them, that I am giving up. Who did all this, but me? She says if I send them at a shelter next week, make sure she is at work. I am really sick of being the only adult in my household, it is not fun.
