Shortly before turning 4 years old, my cat was diagnosed with hypertrophic cardiomyopathy by a referral vets.
Her heart murmur changed to grade 3 and also she had to spend two nights on a drip in the vets because she stopped eating and had hyperthyroid symptoms. I have been told her heart murmur is now grade 4/6. I would be very grateful for donations, thank you in advance.
Update: Snow has passed away, I intend to get her cremated.
