Two weeks ago, I received the 'raw starter pack' from food4cats and was impressed until I noticed several small flecks of metal amongst the wild rabbit chunks. I thought it must be bullet residue and that I was just unlucky with this particular batch, but I have now found a much larger (baked bean size) lump of metal in the wild rabbit mince. As a life-long veggie, I have never eaten or prepared any wild animal meat before so this might sound really dumb, but am I right to be concerned? Or is it fairly common to find small pieces of metal? My kittens licked their bowls clean but fortunately they left this lump behind.
