Most cats adore ceremonial magic. Back when we had one, any time I started to set up for a magical ritual, she would come scampering in, curl up under the altar, and sit there purring and radiating kitty bliss. Yes, they like the Celtic Golden Dawn material -- in fact, the only magical practice I've ever done that cats didn't like is Enochian magic, which sent ours into the back of the closet to hide. (That's one of the reasons I stopped doing Enochian magic and don't recommend it.)
