Toy Basket Catnip Tumble

If you set it, the cats will eat it. If you sow it, the cats don't know it.
Philip Miller, The Gardener's Dictionary

This saying came about because fresh catnip is supposedly more attractive to cats when it is bruised & transplanting catnip bruises the leaves. I don't know how much truth there is to that, certainly my cats will have a nibble on the catnip I keep in their enclosure, which hasn't been bruised.
Catnip is usually fairly easy to grow, you should be able to purchase the plant from your local garden centre. It likes light sandy soil, and grows best in full sun.
Most pet shops either sell catnip toys, or tried catnip. When storing catnip, put it in an air tight container, in the fridge or freezer.
To dry fresh catnip, hang upside down in a dry, ventilated area, away from the sun. Cat-World

Showing off for company this morning, Raspberry tipped over the cat toy basket and found her favorite catnip pillow and totally enjoyed herself.

For the Record,
This came in like an early September day, warm, sunny and almost hot! My brother sent this snowman photo from our summer place in Maine!
