Content: Research on cat behavior at night shows that even cats who have developed sleep patterns similar to our own still wake several times during the night. Once she’s awake, Fluffy shifts into play mode, leaping at your every movement in bed, trying to entice you to play with her. How To Encourage Your Cat To Sleep At Night
Simply locking her out of the bedroom at night is not always effective. She may yowl and pound at the door to be let back in. The best solution is to increase her activity level during the day so that she sleeps at night. This can be problematic if you’re away from home during the day, but it is possible to create an environment that stimulates her and increases her daytime wakefulness. Here are a few things you can do to provide a more stimulating daytime environment: Install A Window Perch
This will allow her to see outside, keeping her engaged so that she sleeps less during the day. You can purchase a standard perch that functions as a shelf or hammock that attaches to the window ledge, or you can install a feline window box – a sort of “kitty solarium” – that fits into the window jam of double-sash windows. Both enable your cat to watch “Cat TV” all day, observing butterflies, birds, squirrels and other wildlife in your yard.
