How can I train my new pet to sleep when I sleep, and play during the day?
Cats are naturally nocturnal. If you're having problems with your feline pet indulging in the 3 a.m. "racing circuit" around your house and over your bed, you need to set up structured, vigorous play time early in the morning and several times in the evening, when you're home.
An old, and true, adage is: "A good puppy is a tired puppy." Exercise causes endorphin release in the brains of dogs, just like people. Consequently, if you want your puppy to sleep all night, and be well-behaved in general, he MUST have adequate exercise. Options include: play sessions several times morning and evening at home; spending the day with a neighborhood playmate (both households will benefit!); going to the dog park; doggie day care.
If you keep your pets awake when you are home by training and playing with them, and make sure they get adequate exercise, they'll adapt readily to your schedule.
