Lol maybe he had...or maybe he fell in his water bowl
Does it smell like urine? Is it actually urine? Could he be blocked up, is there any blood passing?
If it is urine then have him checked for Urinary tract infection, can be fatal in male cats, usually de sexed but not always

If your cat is not neutered he could be spraying the house to show that is his domain to other cats, male cats also spray to attract females to mate.
