The best way to stop a cat from incessant meowing is to have more cats. THEN you have to tolerate the nightly game of Thunder Paws as they race around your house at night!
This activity, Thunder Paws, tapers off about age 7. That is the age cats tend to sleep most of the night.
I’m familiar with Thunder Paws. My youngest is the Household Champeen. My tomcat is a bit above the age limit but still plays. Maybe the younger one keeps him in the game.
My girl kitties have to be around 10, 11...possibly older (We’re not the first owners and they were full adults when we got em) and the 6 year old boy kitties can still entice them into Thunder Paws AKA Feline Derby anytime they want.
