Someone posted here recently about a really noisy kitty (Bengal?) and I recall a couple of other posts dealing with this. Thought this tip might help.

Chatty Catty?
By CatAge Staff

Giving your cat the silent treatment may discourage incessant feline chatter.

Although transition, grief, and medical concerns can increase vocalization, relentless meowing may just be your cat's way of getting your attention. Feeding, petting, or any other response encourages continued noisiness. Instead, ignore your pet's chattering. Once she or he is quiet, reinforce good behavior with treats and affection.
