My 6 month old tuxedo recently started meowing for hours during the night. He’s always been pretty vocal, but now from about 4am-7am he walks around meowing non stop- before and after being fed. I ruled out any health issues. I play with him a lot before bedtime to tire him out. I’m thinking it’s out of boredom. He has alot of toys and things around to play with. I don’t know what else to do. Any suggestions?
