GW,it seems to me from you telling us about Matsi and how she behaves,she still has a lot of living to do.
I don't think there is one person on this Forum,who would not go to great lenghts for their animals.
I chose not to put my 14yr old cat through cancer-treatment,not that the vet suggested it,because once he was diagnosed with Thyroid-cancer it was already to late for him..he was my little soul-mate and I loved him so much,so don't ever let anyone tell you it's just an animal.
To me my animals are as important as anyone else,they are family and I know you feel the same about Matsi.
They give us unconditional love and make us smile if we are down,my house would be empty without four-legged pitter-patter.
