why does my male cat keep crying at night? he does this every night he is 2 years old and was castrated at 7 mths old he is a house cat and has only been out when he went missing for 2 days about 6 months ago. My other male cat is 10 1/2 months old and also castrated but he doesnt cry like this. the cry sounds like a queen on heat calling for a mate. I know that he is not in any pain. He has free access to fresh water and food and the litter trays are always clean. This is really starting to become a problem now as it goes on for about half an hour to an hour every night.
