I have recieved many wonderful and helpful emails. I wanted to share some of the ideas with you all. I"m still undecided, but I'm able to make an educated decision now I think. Here are what many of the repsonses said: 1) Concrete, and use sealer. Its been done many times in room on Trading Places. The cheapest option. It would be very cold though lol. 2) Linoleum. The second cheapest. I was told that if I go with the best, thickest, and a good design it would be beautiful. I was told by one fella you can lay down a type of under stuff (I forgot the name of this whisperboard stuff) that would help insulate it plus make it quieter. 3) Pergo laminant wood flooring. Very expensive. Beautiful. Hardy. Good for ferrets. I had two emails with concerns that the seams would leak the urine over time. People who have it seem to love it and stand by it. 4) Tile. Many people say you can seal it the grout. Shelters have tried this and say there is no way to 100% seal the grout, and it is not as hardy as other options. You would definately have to reseal regularly if you went with this. 5) Combinations. I had some creative ideas sent to me, such as installing subfloorings on frames in the room, so it wouldn't get so cold. I had this one email with this really creative idea, where she had linolium around the outer edging/perimeter of the room, and then rug in the middle. Then when ferrets make mistakes it won't be on carpet. she glued down replaceable carpet squaring in the middle of the room. :) Thank you so much to everyone who has an continues to help me learn about flooring and help me decide on what to do in our room that I want to be cohabitable by both species. :) Wolfy Please visit: http://www.geocities.com/wolfysluv/ for information on ferret deafness: http://www.geocities.com/wolfysluv/deaf.html [Posted in FML issue 3751]
