Mine were on Burgess Excel with Blackcurrant and Oregano. I saw the Asda ones and, like you, thought that at that price there must be something wrong with them, but when I compared the ingredients they were virtually the same as the Burgess. I gave them a try and the piggies loved them. In fact, when I couldn't get to an Asda to restock and had to give them Burgess again they turned up their noses!
