One of my cats is so addicted to grass, since the day I got him he craves and eagerly devours grass. I have bought pre grown cat grass and since its nice out im growing my own outside from a kit. I never use chemicals or fertilizer ever so its very safe for him. But 99% of the time after eating the grass within a minute he pukes, sometimes its just saliva with grass, other times it's undigested food with the grass.
My other cat doesnt crave grass, but she will eat it once in a while. She almost never pukes after eating grass, ill see it in her stools a day or two later.
Why does one of my cats crave grass so badly and always puke after? Is there something wrong with him because my vet said nothing about it other than to avoid grass treated with chemicals, but it seems very odd to me how he wants it so bad all the time.
