I don't even know where to begin to describe our experiences since getting Serenity (formerly known as Godiva).  Serenity has been a great addition to my four legged family.  She can definitely be a bundle of energy.  I was a little hesitant about getting a cat at first because I have only had dogs (and fish) in the past.  I must admit I am extremely happy with her!  She gets along well with her two adopted sisters, and I sometimes take her to a friends house to visit a cat friend.  With her cat friend they get to run around the house chasing each other and wrestling - things she doesn't do with the dogs.   Even with all of her energy, bedtimes are the best with Serenity - she is a cuddle bug.
