Definitely sounds like it, especially if it smells very strongly(the nasty stuff makes me sneeze and makes my arms itch).

If you want a good bedding that holds humidity and won't mold(and is still fairly soft), why not try Home Depot or Lowe's. You can get a big bag of shredded/double milled cypress mulch for around $3. You may want to bake it in the oven(250 degrees until dry-will make your house smell foresty) if it is wet, but I've even used it wet and have not had any adverse effects with it(Amani does have softer skin, LoL). It can be a little more difficult to spot clean, but I've found if you keep a sheet or two underneath the mulch, you can see how big the area of urine is and can adequately clean up.

Alternately, you can get aspen. It is very light-colored shavings and can either be chipped or shaved. Shavings are what you are looking for as they absorb liquids better and are softer. Do not get these shavings overly wet for too long of a period, or it will mold(nicht gut). You can find compressed bags of this at WalMary or Petsmart(or other pet store) for a very reasonable amount. I tend to prefer the aspen at Walmart as it is very finely shredded and soaks up moisture like nobody's business.

I hope this has helped a bit!
