cat crying

Question
For the last several months our 17 year old cat has been crying loudly through the night.  He doesn't start until everyone has gone to bed and the house is quiet.  Any idea what's going on?

Answer
Terri,
      I am concerned given your cats age that he may be experiencing the symptoms of Kidney disease. Occasionally when cats start to have Kidney problems, they will alter their eating patterns and become stressed when they go to feed at night and don't find food or have trouble processing their meals. Additionally, he may be requesting fresh clean water.
The problem could also be related to various other forms of stress or even boredom. Cats and dogs will experience similar aliments as they age, as humans and he may be forgetting the fact that this is the usual pattern. If he is unable to come in contact with you, he is communicating his uneasiness. They best advice I can give you, is to have him examined by you regular veterinarian to rule out any medical related conditions or problems. Request your vet to run a blood panel. He will be able to determine if your cat is experiencing Kidney, Liver or Heart problems, and offer you the proper treatment.
Keep in mind that 17 is a very old age for a cat, and that the problem is most likely related to his age and a medical condition. If he receives a clean bill of health than the problem could very well be behavioral. If so, try and keep the bedroom doors open and allow him the opportunity to go from room to room.
Also, lay down fresh food and water before you head of to bed for him. Try leaving on a radio with soft music or a talk station, to comfort him, or leave the TV on for him.
Again, I must stress that it is for the best that you rule out and medical concerns, and than go from there. Some cats can live in upwards of 20 + years so; don't feel alarmed if a medical condition is ruled out. As I said it may be behavioral, and you can them treat it accordingly. You can discuss the use of drug therapy with your veterinarian to help in the problem as well. There is several indicated behavior modifying medications that he can prescribe, such as Buspirone (Buspar).
Finally, I suggest you research and possibly try a new product on the market called either; Feliway spray or Comfort Zone. These are both pheromone releasing products that aid in calming a cat and solving such behavioral problems. They are available over the counter at most large pet supply stores.
I hope this offers some help in solving your cat's nightly escapades and allows you to finally get some sleep. Please feel free to get back to me with any additional questions or concerns.
