I hope that you are doing okay over there. Loss is so hard.
On 2/7, I lost my boy to hemangiosarcoma too, he had a 7cm or so tumor in his spleen, several in his liver, the largest about 5cm, and spread in the omentum. Evil beast of a disease.
Like Raggs, I had some bonus time with him, though I didn't realize he had hemangio at the time, just that he was very sick. The ultrasound last summer was completely clear.
You and Raggs fought a battle against disease, but a battle filled with love. I hope that that brings you some comfort, as there are about no other good tools against these diseases.
For our boys
