I just returned from taking my 14 year old cat Millie to the vet for her annual exam and blood work. Everything but her heart and weight checked out clean. She now has a slight difficult to hear heart murmur and her weight has dropped from 7lbs down to 5.15 within the last couple years(last year she was around 6lbs). I'm wondering if anyone here has any experience with what our possible culprits are for this. Hypothyroidism, Hypertrophic cardiomyopathy, kidney failure or cancer...its possible it is her teeth as well as we haven't done a dental in a few years due to her age. I won't receive the test results until this weekend...so any feedback on what I may be dealing with if any of you have dealt with any of the above would be great...thank you all.
