We all know that tawnyspots died a painful death due to a painful lump to the stomach. what was the cause? i believe it was a cancerous tumor in the lump. tawnyspots was in a LOT of pain as he died. that is a sign of cancer. my step grandfather is a retired veternarian (or cutter) and i asked him if cats and dogs can get cancer and he said 'oh yes they can'. did tawnyspots die of cancer? what did yoy think?
