Cat addicted to grass

This thing is though, cats have a very short intestine which means they can't actually absorb any nutrients from grass or any kind of vegetation. She may love to eat it, but it all comes out the other end undigested.

I do have a couple of pots of grass for her which she tends to treat like toys. Many is the time I've gone downstairs to find them both upended, dirt everywhere, and a very soppy kitty having a roll in the mess she's created. Once she managed to pull the grass free of the pot and carry the whole lot upstairs to the bathroom matt!
