contemplating a new floor...what should I do?

I have read about 100 threads on everything I could think of but can't find a complete answer. I'm in a condo on the 3rd floor with all wood construction. My cat decided to pee in one corner of my room while I was gone this past weekend and it started wreaking <-- is that how you spell it? Anyways I pulled up the carpet to see how deep it penetrated and upon doing so I found that the mud bed was starting to crumble in that spot. I got out a chisel and cut out about a 2 inch thick piece of mudbed to reveal an OSB sub-floor. My whole condo is sitting on a mudbed with carpet everywhere except the kitchen and bathroom, which is tile. I had planned on ripping out the carpet prior to this incident but have not decided on a new floor material. I have a dog and a cat and frequent the pool and beach so I would need something resistant to water and scratching...should I go vinyl? Can you stain a mudbed like you would concrete? <--- stupid idea? They (the contractors who did the carpet last) nailed the carpet tack board thingy's along the baseboard straight into the mudbed which has cracked it in it's path. My guess is it's cracked throughout the entire place...should I rip the mudbed out and just lay pergo? or repair it with sakrete and tile\vinyl over it?

Carpet over the mud bed?? Mud bed over OSB?? If this is so, then it is likely the mud has cracked throughout the floor. As wood expands and contracts and any movement in the wood subfloor will cause mud to crack.

Are sure it is mud over OSB over the entire floor? A pneumatic chisel can be used to remove the mud. This will not be a small job.

The integrity of a floor is as good as what is beneath it. Depending upon condition of the mud subfloor, it may be possible to patch affected areas and install floating floor. Mud subfloor would need to be 'flat' and smooth.

What your looking at is a typical lightweight, gypcrete substrate.

Unfortunately the only thing that is OK over that is carpet, a floating floor, or ceramic with Shluter Ditra. Then double unfortunately, floating floors and ceramic will need a lot of floor prep over that junk, if you want it to last for any period of time.
