Are sprouting beans good for cats? I am not a rabbit.

Dear George,
I seriously wonder if my mummy knows the difference between a cat and a cow (yes, I know…both start with a “C”) or rather said between an herbivore and a carnivore!
I am saying this because for the last three weeks she is trying really hard to grow something for me, something that she calls “sprouts” (photo attached). I mean take a look at the photo and tell me how on earth does she think I’m going to it that ugly, unappealing stuff? She’s telling me that it’s winter and I don’t have any grass to chew on if I’d like to. But, for God’s sake then just grow some grass for me.
George, can you post a list of “greens” good for cats? PLEASE!

Yours truly and always,
CAT Victoria

Long digestive tract with huge caecum

Dear Cat Victoria,
I can't post a list of greens that are good for cats. But there is a list of human food which is poisonous to cats here. Grapes, raisins and onions (even in gravy) are on this list. The more you eat of these dangerous foods, the more poisonous they are. 
A little vegetable is probably good for cats, but not too much. We humans, and dogs,  are omnivores, and are designed to eat both meat and also vegetables. Cats are not.
Cats are "obligate" carnivores, meaning that their intestines are designed for meat - the whole carcase, skin and bones, not just flesh. You can see this in the illustrations here which show a a rabbit's intestines (an animal that is designed to eat nothing but vegetation) above with a cat's digestive system below. The rabbit (above) has a long intestine with a huge wavy pouch called a caecum which breaks down the cellulose in vegetables, while the cat has a short intestine with a small caecum which you cannot even see in this illustration. 
Here in the UK, you can buy special grass for cats. I think you would enjoy that better than sprouting beans. I know I would.
Yours
George
