Two piggies I had from a member on here said they had P@H nuggets so we bought a bag for them - tried our other piggies on them and they didn't like them. Weaned the duo onto the Wagg Optimum and Burgess Blackcurrant & Oregano and loved them. All of them suddenly decided they didn't like the Burgess anymore recently :{ so they only have the Wagg - £17.49 for a 10k bag from Amazon, free delivery, lasts them around 2.5 weeks and saves us running low on them as I just order every fortnight.
Bought the new Supreme Science FibaFirst on Sunday so they have some of that too with their approval rolleyes
It is in a stick form so pop a couple in each of the piggies hay baskets and they forage for them
