I don't think that's feverfew - I think the the leaflets of feverfew are broader and shorter.
But I'm not convinced its cow parsley either - it just isn't quite right - but cow parsley has lots of similar relatives.
Have a look at the leaf stems - if they have a groove or channel running along the upper surface then it's likely to be cow parsley Anthriscus sylvestris.
I'd be more convinced if I could crush the leaves and smell it. I spent my childhood picking armsfull of cow parsley for our pet rabbits.
