I ended up bringing mine indoors too putting it in a south facing window .. cut off the horizontal leaves and the pointy spikes on the remaining leaves but didn't do anything with the serrated edges. Doesn't look like it stressed the plant at all. I have noticed a little kitty fur on one of the leaves so hopefully they got the message to leave it alone and told the other kitty to leave it alone too.
Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so.
