I'm sure that is possible.. maybe his old 'chicken' diet was loaded with turkey, duck and other proteins, and I didn't even know it. (I suppose 'meat derivatives' on the label could mean anything.. and I probably don't want to know what!).
Unfortunately it is pollen season so my cat's food allergy problems are being made worse by his environmental allergies. Last night was very bad - he was scratching all night, and rubbing his face - which made his eye start watering. He is also losing hair on his eyebrow area and is understandably very agitated.
I gave him more anti-histamines but they didn't work, so we ended up at the vet today for a short-acting cortisone shot. I don't like giving him cortisone, but didn't see an alternative. At least he is looking a little happier now, poor thing.
None of the foods with the 'correct' ingredients have worked.. they are either ignored or cause a reaction. And he doesn't enjoy meat at all - cooked or raw.. but I suppose you are right Akita, the elimination diet has to be cruel to be kind.
I must start him on a new diet this week.
If I consider his blood results, the best choices for elimination diet are rabbit, pork or white fish (or a novel protein - but there are really no novel options for him.. as he has eaten nearly everything!).
As my local butcher doesn't have rabbit - and pork is quite fatty - it seems fish is our best option..
So what if I put him on a white fish diet for several weeks and go from there? Is it safe to feed him fish in such large quantities?
(Another thing worries me about fish - I think it might have caused him allergic reactions in the past. So if he starts reacting on the diet, i will have to discontinue it immediately).
Otherwise I see NATURE'S MENU have a range of raw foods available which seem very convenient - they deliver frozen ready-meals direct to your door. (This would help me a great deal as a single mum!) Unfortunately all the raw food options include chicken as an ingredient, which is another one of his suspect proteins.
Do you think I should try it anyway? Does the fact that the meat is raw make any difference?
