https://www.vetsurgeon.org/f/clinical-questions/21818/heart-murmur-in-6-yo-cat Apologies for the basic question. Could a cat acquire a heart murmur ( grade 3) post trauma ( RTA with degloving injury to limb and potential compromised vasculature to the point where it may need amputation), blood loss aside?

I really do think it&#39;s circumstances. Your post made me feel a whole lot better! We&#39;re house call so minimal stress ( or that&#39;s the theory!)</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/131435?ContentTypeID=1Tue, 10 Mar 2015 18:51:37 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:27673215-7b63-4681-976e-816ddae9313dKate Richardson<p>Yes. Cats can develop heart murmurs for all sorts of reasons- anaemia, pyrexia, dehydration, stress, as well as cardiac disease. How is the cat when examined- stressed or relaxed- what&nbsp;was the heart rate on each occasion (murmur heard or not)? the higher the heart rate the more likely a flow murmur can be heard. So you&#39;re hearing may not be bad, it may be your cat handling skills are better! </p><div style="clear:both;"></div>
