I moved about a month and a half ago to another state with both of my cats. At our previous home, both cats went outside for at least several hours a day, and in the summer spent most of the night outside. Since the move to a living space where they can't go out at all, one cat has adjusted, while the other talks all night. We've tried the ignoring and letting him get used to it. But we haven't had a full night's sleep since we moved, and my fiance is ready to ask me to take the cats to my mom's house to stay there during the 2 years that we will be here in NC. I learned about a corrective device that can be used on dogs and cats, you press the remote towards the cat doing all the meowing and it emits a high pitched sound. The cat will associate his meowing with the high pitched sound and stop. Has anyone ever used something like this? I don't have a vet established yet here but I wanted to call one to see if this is a viable option. Any suggestions?
