We just recently this past labor day got 2 brand new ragdoll kittens, we have recently now let them out to play. Our older cat still isn't too sure and still hisses and screams at the new kittens and yesterday she swatted at one of them. These 2 kittens are very curious and the little batteries in them haven't stopped since. Is there anything we should maybe get and do with them to keep them busy, they are started to be slowly on a schedule. They are totally different from past kitties and our oldest cat ( who is super lazy)
