Thanks everyone! I copied and pasted the responses here and sent them to my friend. She misses Spazz snuggling in her bed at night, but has done the separating thing, and it is working a lot better.

Even now, Spazz might jump on Cuddles, but not as badly. She is thinking the move really set Spazz off, although she was like this before.

So...another kitty life saved - which my friend would have done only as a very very very last resort.....and even then....

thank you all so much!
