Your cat just got a new play mate, one with her level of activity, the husky! A 15 year old cat - Siamese or otherwise - is just not going to bring out the kitten side of your cat. The older cat did set an example of how to act, and the young one emulated that. Now, she is seeing another example, and it is FUN! Kitten crazies are pretty normal around here, especially up to 2 years old. Then it does tapper off a bit. Beware of the oven and refridgerator, as you have noticed, also the microwave and the washer and dryer. I always leave the doors closed, even when not in use. A spray water bottle will help train her that countertops are off limits. Then sit back and enjoy the show!
