I know cats are nocturnal, but it's driving my fiancee and I nuts. We found out that Cinnamon was already fixed. We keep her up, nothing, try to pet her all evening, nothing works. She meows constantly when we're trying to sleep. We're at the point either two options; 1, we get sedatives from the vet, or 2, we give her away. We can't let her meow because we live in an apartment complex and the last thing the neighbors want to hear is a cat howling. Any suggestions from anyone?
