Thanks everyone, first let me say, sumi WENT today! Yay for poop! This after I gave her a teaspoonful of cod liver oil, neat, which of course she loved (this kitten eats everything). Baloo, it's Natascha's Instincts I order, just this order is delayed, so I'm giving them morning raw meals, with egg yolk and a tsp powdered eggshell, and then for evening meal Applaws wet, or Lily's kitchen organic, so they get their nutrition. I wouldn't give them extra liver - they only need a tiny piece per day, and if i'm not including raw, I put the requisite amount of Instincts liver powder in. The Lily's kitchen organic is excellent food - no fillers or grains, min 60% pure organic meat, so, no rubbish going in there. Having said that, raw so clearly has many more benefits for life-long overall health. I am concerned about different digestion times if I feed raw and commercial. At the moment I am waiting minimum 6 hours after raw before feeding Applaws or Lily's, and more like 12 hours after commercial before giving raw again. I do this because I am wary of allowing the raw to back up in the gut and cause bacteria problems, eg, salmonella. Some advise waiting 24 hours with commercial, but I believe that is cereal-filled rubbish they are considering. Others actually mix raw and commercial in one meal, and are not in the least worried about any health risks. It's early days for me yet in the raw game..
