https://www.vetsurgeon.org/f/clinical-questions/5685/tuna-in-brine---myopathy-link I have recently seen a 10-year-old DLH with acute onset bilateral myopathy of the quadriceps/gastrocnemius muscles. Routine bloods were normal apart from raised AST and very high CPK.

The owner just would not listen to me so I referred her to Bristol Feline Unit and they performed every test under the sun and came to the same conclusion&nbsp; - feed a sensible diet. Obviously &pound;1,500 of investigation is more convincing than a consultation and an x-ray! However I confess (and this is when I was small boy so I&#39;m an innocent party) my mother insisted that our cat would only eat Marie Elizabeth sardines in olive oil - John West or tomato sauce would not do. When I think about it now she would have been the client form hell&nbsp; - I pity the poor vet we went to.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/22148?ContentTypeID=1Fri, 06 Aug 2010 21:09:20 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:cd9ac56b-c526-4814-805e-03bf2310a321Bob Russell<p>There were comments made at a symposium in the US suggesting a possible link between high tuna diets and hyperthyroidism. It was suggested that as the top of the food chain (other than us!) heavy metals can be found in high concentrations in Tuna. This would make some sense when you consider the weight of a cat and the contents of a tin of Tuna.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/22133?ContentTypeID=1Fri, 06 Aug 2010 18:36:49 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:39d52b06-c6ed-4726-b9f0-fe8b36b44026Joyce Whitehead<p>I once saw a case similar to this (many years ago), and found it had pansteatitis (yellow fat disease), which occurs I think as a result of high fish diet, leading to hypovitaminosis E.&nbsp; The one I had was a young cat, and came in to be spayed just after the apparent muscle pain episode, and I noticed how yellow the fat was.&nbsp; Somewhere in my brain it rang a bell.</p> <p>The solution I&#39;m afraid is mainly to reduce the amount of fish in the diet, and possible supplement with vitamin E as well?</p> <p>Hope that helps!&nbsp;&nbsp; <img src="https://www.vetsurgeon.org/emoticons/v2/Happy_smiley.png" alt="Happy" /></p><div style="clear:both;"></div>
