bednobs, one's cat must stick one's apron on, ensure a quick escape route is planned should any plant pots crash to the ground, and read the following link's step-by-step instructions carefully:

Then, ones cat should ignore the above instructions, bung both the seeds and the peat disc/ pellet into the bag with enough water to make the peat expand and go soft, chuck a peg on t'bag and whack it into the back of one's owners fridge for a week.
Then, said cat may remove apron, saunter off to a nice warm corner and dream of the days when there will be fields and fields of catnip to roam in...

good luck!
