I think my kitty is sick? ): He has clear liquid coming out of one eye?

My cat became sick after he was neutered too. The running eye is very normal for cats so no worries. If it sounds like he's got a stuffy nose run a hot shower and close the door.. and lock him in the bathroom. the steam will most likely cool down his nose. If he gets any worse take him to the vet! Good luck and hope he gets better! :D
