This is not an April Fool's joke.
While I am all for good and humane treatment of Animals, to apply Human Rights (see the Universal Declaration of Human Rights) on them might be just a tad too far. Examples being Articles 24 and 26. And also, with rights comes responsibilities: see Article 29.
What we need is a comprehensive set of Animal Rights that govern our relationship with them. In some cases, there should be protection at a level above what we grant to our fellow human beings... or five year old human beings. Maybe a modified version of the Rights of the Child for our closer hominid siblings?
And dolphins. Must not forget dolphins.
