Cats aren't social species, they don't have the capability to understand what is and isn't private. If a cat wants to lick its balls it'll do that, even if the owner is watching.
Also, even if we wanted to push for some sick agenda that cats should have rights too, you can't really make a cat aware of said rights. Cats dont give a shit about cameras watching them
People are not concerned about private data being broadcasted of our feline overlords.
