I saw in the store today some grass you can grow for your cat. Now I have a weird story about that kind of thing but I am sure it is a coincidence. Maybe. Years ago I had a cat who was about 6 years old. One day we bought some of this grass and let her have some. The next morning I found her curled up behind the couch, she Since then I have never ever even thought about buying it and I won't for any other cat I ever have. I don't know, maybe it was a coincidence or do you think it could have been dangerous for her?
