1. Provide multiple levels of lounging /playing space for your cat. Cat’s love to be up high and survey their catdoms. Get a cat tree, or provide shelves so kitty can have some vertical fun.
2. Cats also like to hide. Find a box, or buy a sack type bed, and put it in a secluded area of the house.
3. Provide self-play toys like balls or other small toys that can be batted around or attacked. Soft toys that kitty can get a grip on are good for this. I have yet to meet a cat that does not like these. Leave them out for playtime. Kitty will use them when it wants to.
4. You must engage in interactive play time with kitty at least one time a day. A pole with a string and something fluttery attached are good for this. Let kitty chase it, hunt it, and “kill” it. Do this before bedtime and kitty is less likely to meow.
5. Kitty meows, because you are responding to it. Try the things listed above, and stop reacting when kitty meows. It will be annoying for awhile, but when kitty doesn’t get a response, kitty will unlikely meow to get attention.
Good luck! Cats are wonderful, and can be trained. Well, more like the human can be trained to deal with a cat. = ^. .^ =
