The cows connected to the internet

Note that all cows (and some other farm animals) in the EU are already subject to legally-mandated "inventory tracking", of movements between farms. This is for epidemic control purposes following the last outbreak of foot-and-mouth disease.

I knew someone who did a PhD on analysis of the cattle movements database..

Now you just need to create a twitter account for these cows. They could tweet things like "Nice hay today!" or "Feeling a bit gassy, going to lie down." the kinds of things Cows might tweet if they tweeted.
