Just thought i would let people know, Lidl are doing a "living salad" in a small tray for 99p. Its consists of various lettuce leaves (red & green) and lasts for ages. I bought some about 3 mths ago and keep picking at it as part of Sammy's diet. Its handy for new owners to know as your never quite prepared for such a varied diet in the first year (and often get funny looks while collecting weeds out in public!)
