Content: Get A Birdfeeder
Birdfeeders that attach to windows with suction cups are very popular with indoor cats, and will hold their attention for hours. Or, simply hang one near a window from which your cat has a view. Adopt A Companion
If your cat is an only cat, consider adopting a companion for her. It will decrease her boredom and increase her activity level during the day. She will direct her nocturnal need to play away from you and toward her companion. 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.
