Vegetarianism makes him sick!

The internet is going wild over a video of a carnivorous lion chowing down on grass in India — then promptly tossing his cookies.

The ferocious furball is shown grazing in India’s Khambha forest before coming to terms with his inner meat eater, footage posted by The Times of India shows.

The big cats sometimes munch grass when their stomachs are upset, experts said.

“They eat grass to vomit out some undesirable food they have consumed,” conservationist Sandeep Kumar told the paper.
