I read about this changing somewhere, because NM were having problems with their suppliers (ingredients?) or something like that, and this has been resolved by a change in supplier - but it sounds like a backward step then if its changed to made in EU rather than UK? I havent used it for a while anyway.
Its going to be hard to find decent high meat content wet foods made in this country without artificial flavourings, preservs. and colourings etc soon - only one I know for sure, is Forthglade - from their site
'wholesome products made in the heart of Devon, with most of the ingredients sourced from the West Country' Not sure about Natures Harvest - think made in this country, but don't know where ingredients are sourced - although it does say it uses Scottish Salmon oil
