Many many prayers gong out to you. Perhaps if they had replaced the carpets when they should have, there would be no smell.

After the carpeting is installed, maybe the 4 could be back with you? I guess you can't afford to move?

Best of luck - I hope a PTr can give these babies a home.

I'll check with my FB contact in your city and see if she knows anyone (I think she has 3 of her own).
