We have got some mince that has lungs and hearts in it (economy mix) from Landywoods as well, they have had no problems with it either .

Thanks for that nndogs. Ben is a fussy git, just like his dad. I think the problem is I gave them raw lights on their own, instead of using my commonsense and making them less "spongy" and more appealing. He will eat them raw provided they are mixed in with some landywoods mince, or some cooked lights. I cook them for the cat - I have tried her on raw food in general, and she just won't touch it, but she turned her nose up at raw lights!
