Hi guys, I have a concern. We have two female cats and they are both spayed. Their pee is odorless. Our newest addition is a male, 1year, and he was neutered three weeks ago. His pee smells AWFUL. I thought perhaps the pee smelled worse because he wasn't neutered, but it's been three weeks. Does it take longer? Will his pee always stink? Is it a health concern? Thanks!
