thats brilliant! thank you so much for the advice and for the links, will go and look - that was one thing I wondered about, if they would sit nicely and chew them over their bowl in the kitchen or not lol! as we have new carpets I dont think Id be that chuffed to have gristle and chomped bone ground into it, so as we have a decent sized kitchen I may shut the kitchen door while they eat it then! if they take to it that is - Im interested in whatever natural means I can use to keep their teeth clean, and also the issue of taurine with it being depleted in cooking, is it ok to give the kidney and heart raw as well then?

thanks again! xxx
