I've been reading a lot more on the net with people saying that cats do and don't get into the different varieties of catmint, and as much as I like to offer more flowers to the bees and butterflies, I don't want the cats coming into my yard any more than they do already.
I feed the birds and wild rabbits every day (in feeders and on the ground) and the cats have killed the birds and chased after the rabbits, so I decided not to grow this plant. I don't want to take a chance.
Thank you all very much for the replies and the information!
