I had to deal with something similar... but we have no concrete under our house... so there were a few cats living down there. We had some fun chasing them out of there... luckily they didn't have kittens... but I was prepared for it. Sucks that you have to do some 'remodeling' to get to them. Interestingly enough, my bathroom is ripped apart because we're re-doing it. I feel like I'm getting old when I have to do stuff like this... but it's so fun! Ok, I'm off topic. Your wifey gonna try to get you to keep them? lol Hopefully they find a good place to call home.
