PETA has undergone a promotional campaign to make people more empathetic towards fish by calling them ’sea kittens’.
“PETA thought that by renaming fish sea kittens, compassionate people who would never dream of hurting a dog or a cat might extend that sympathy to fish, or sea kittens,” PETA campaign coordinator Ashley Byrne says.
However when asked why they didn’t just rebrand kittens as ‘land fish’ PETA had no comment.
