OMG this is SO wrong. Those people are keeping a predator as a pet. An animal that's specialised on hunting and killing other animals and solely eats meat, can't even digest anything other than meat and very few other substances which all come from animals. And then they want to feed it vegan food? Arrrr.......
One shouldn't force veganism on an unwilling living thing, especially on one that needs meat to survive. I'm looking at you, PETA...
I'm not anti-vegan.....but that's just wrong. The correct consequence would be to spare the cat and NOT OWN ONE.
