She won't eat the cat grass!

I bought a special pot of cat grass for Persia and it's about 5 inches tall
now. She has sniffed at it but she won't eat it. I'm not sure if this is
because she knows not to eat my other couple of houseplants and thinks
she'll get in trouble if she does or maybe she just doesn't like cat grass.
I'll give it another few days and then if she doesn't like it I'll toss it,
I guess.
