FWIW here's the EU regulations relating to the transport of live animals.

I fail to see how animals are likely to suffer more on a 1hr crossing on P&O than while being transported down to the Port.
It is a shame that the protesting fools are forcing the animals to do a longer crossing in a less stabilised vessel but as with opposing hunting it's all got bugger all to do with 'animal cruelty' as opposed to making them feel smug and worthy.
As for opposing 'animal testing in laboratories' I just hope the stupid, stupid opponents don't ever suffer from any of the countless diseases and infections which have relied on animal testing to produce the drugs we all use.
A few facts here - but I don't expect a few 'facts' to change anyones mind especially when a leading scientist (sic) on the internet said we no longer need to do it.

As I've said before I have two siblings with MS.

If animal experimentation can save others suffering as they do so be it and sod the misinformed bunny huggers.
