I was in sainsburys getting some cat food for my mums cats and michael pointed out the cheapy cheapy sainsburys basics and I pulled a face (as you do) and said it was probably not any good, but, low and behold it is 40% meat content! it was £2.50 for 6 tins, but thought I would let people know, I can post the ingredients list if anyone wants it, but was surprised that the sainsburys basics range seems to be better than the likes of whiskas etc.
