BY: -The sleek and regal Siamese is one of the world's oldest known cat breeds, but they are definitely not famous for being quiet. If your male Siamese has not been neutered, take care of that ASAP, since mating cycles can trigger excessive meowing. A veterinary visit can also rule out health issues that could cause frequent vocalizing, such as hyperthyroidism and hearing loss. Most likely your boy is just naturally quite vocal. Try playing with him close to bedtime. Offer catnip-scented toys if he responds to catnip, or honeysuckle-scented ones if he does not react to catnip. These herbs excite cats initially, but then seem to make felines a bit drowsy once the mild kitty buzz wears down. Any sort of playtime will do, however, as the goal is to work off some of your cat's energy so that he won't feel inclined to do that while you're sleeping.
