Catnip

Catnip is the controlled substance of the herbal world. When planting it certain precautions are necessary.

It became pretty apparent to me that this cage was a help, but not adequate.
This plastic screen might do the trick.
I'm sorry that I did not document Abe clawing at this fruitlessly, but he did. Here he is walking away. He'll get his fair share of catnip later on.

I didn't plant this just for the cats. I have found that catnip repels japanese beetles. Really, they will flee when they smell it. Japanese beetles not only love to eat roses, but raspberries. I just planted a heritage red raspberry which was excuse enough for me to spoil my cats.

Catnip also is supposed to repel fleas but I have not seen this. Catnip tea is supposed to be good for lactating women as well. I do not have as 1st hand experience with this either.
