For some pet cats, trashing pot plants around the house is the only reason to stop sleeping in the nearest sunny patch. If you've given up on keeping houseplants because of a feline terror campaign, you might find this hack, using an IKEA plastic bag storer, a nifty way of creating some plant protection.
That use for the $4.49 Rationell Variera bag holder, suggested by Marinka at IKEA Hackers, won't automatically solve all your pussy plant problems. One of the cats in my life takes more pleasure in slashing at the greenery than digging out the dirt, and this wouldn't help with that. But it's a start.
