Put them in separate rooms & close the door between them.

Thanks pirate girl, that would work if I had doors. I live in a studio in down town Portland.

Hang them out of reach? The plants, not the cat of course. =)

amsten,
My family has had many KittieKATS....Ha!...Sorry, couldn't resist... and as PG says, all you can do is provide a physical barrier until your crazy cat has moved on. Usually only lasts a few months. Hang in there.......

Bahhhh its no fun! They are small pup so I have to figure something out quick before he destroys them.

So sorry Amsten, that didn't occur to me, even though I also live in a studio apmt (which is why I don't have cats, no doors).

Assuming you've got a bathroom door, can you isolate either Moose or the plant in there while you're at work?

Upturned laundry basket over the plant.

Locking the plant in the bathroom is a great idea!!! Thanks pirate girl

You're so welcome, glad you think it may help.

I rather like the laundry basket idea, but could also envision a kitty trying to move that around a room.
