well! above all, be patient with them, they're new and need time to settle into your home. they may not care for an excercise ball, they're smarter than that, same with a wheel. i recommend wearing baggy clothes and sticking them up your shirt. they'll love the warmth and will learn your body quickly. they'll love to play in your clothes (while you're wearing them) and become very bonded to you. i put my boys in my sweaters while they were young, and now when i open their cage they try to go up my sleeves lol. sit on your bed with them, they'll run around and all over you. they're smart enough no to fall off the ends. they love to climb like monkeys and use their tails for balance. do not hold them by their tails as they're not meant to hold that weight. theyre young enough to still expect to be taught as though you';re their mommy, so stick 'em in the sweater and in a few days you'll have cuddly babies!
