Naughty cat damage!

I have a vegetarian cat, Marmalade. He is constantly
chewing my house plants. African violets are a
special delicacy to him. I finally resorted to placing
these two plants in a small aquarium where he
has greater difficulty reaching them. If you
enlarge this photo, you will see both his cat hairs
and bites out of the leaves of both the begonia and
violet. I think I have the upper hand....Maybe!
