When my SO took his cat to the emergency vet last week due to some urinary problems (he's all better now), the vet discovered that only one of his "jewels" had dropped. He's 2 and my SO hasn't gotten him neutered because "he doesn't spray." He doesn't, but the vet told him that if he doesn't get him neutered some serious health problems could arise. But, he has to get neutered to get the one jewel that has dropped, and the other one is still in his abdomen area, so they would have to a spay type procedure! Poor little kitty!
