Here's the deal:

Hobo's urine smells AWFUL. We have the litter box downstairs in the laundry room and the WHOLE basement smells the icky smell of kitty pee. We just switched to Fresh Step litter that says is for MAXIMUM odor control. It helped a little. He's not neutered yet, could that be the problem?? We don't know what to do?? Any ideas? Are we doing something wrong?
