After a lot of thinking and a long time of deliberation, we decided to bring Sam and Dax to the humane society. We did decide to keep Sadie. So we aren't completely cat-less. As far as we know, Dax has already been adopted. We don't know about Sam yet, but I like to think she has been adopted already as well.
Here are a couple pictures from my last day with them….I was a little sad. But it was the right choice and everyone will be much happier.
