Content: Increase Your Playtime
Play with your cat in the evening before bedtime. The best toys are laser light and fishing pole toys that encourage lots of running and jumping. In addition to increasing her activity so that she’s tired enough to sleep at night, there are additional steps you can take to keep her from disrupting your sleep: Provide a warm, cozy cat bed in a spare room. Most cats love heated cat cups and will find them to be a welcome alternative to sleeping in your bed. Change her feeding habits
There are two changes you can make to her feeding schedule that can help keep your cat quiet at night: One is to feed her the largest meal of the day just before bedtime to increase lethargy and encourage sleep. Second, if your schedule permits, shift her breakfast time to later in the morning, so that she expects her food later. If your cat insists that she’s starving at 4 a.m. and won’t survive until morning without some Fancy Feast, consider using an automatic feeder that will dispense small meals at programmed intervals. Keep her away from the bedroom door.
