For animal lovers, cat communication can be very mysterious and confusing. According to the ASPCA, a piercing yowl from your tomcat can be so many different things -- from an urgent demand for more kibble to an attempt to lure in all of the local queen cats!
If your cat hasn't been neutered and is old enough to have reached sexual maturity, his cry very likely is a mating call. Male cats reach "puberty" at anywhere from 4 months in age to one year. If he yowls loudly and persistently through the night, he very likely is trying to attract females for mating purposes. Look for other evidence that may support this belief -- such as urine spraying, wandering off and restless behavior. Remember, one very easy way to make this type of crying to stop is by getting your cat neutered. Neutering stops mating behaviors, keeps your cat healthier and also prevents feline overpopulation issues -- a serious and growing epidemic in this world.
Since cats can't speak in the same manner as humans, they have to use other means of communication, crying being one of them. A male cat may be wailing due to simply suffering in pain. If you suspect that this may be the case, schedule a veterinary appointment for the poor dear immediately. A wide array of ailments may cause your kitty to cry -- from cancer to thyroid problems. The sooner you investigate the situation, the better for you and your beloved pet.
As tough and cool as your cat may seem on the outside, he probably craves attention and love along with the best of them! His crying may be a simple demand for your undivided attention. Think of it as his saying to you, "I'm lonely. Pay attention to me. Play with me. Snuggle me." And then actually do all of those things!
Cats look sweet and innocent, but also often have very demanding streaks. By crying, your cat may be demanding that you do something for him -- now. Perhaps he wants to go outside. Maybe he wants you to feed him -- even though he just ate half an hour ago. The possible reasons are endless -- and it's up to you to figure out the answer!
