i.... i think this could use a different name. Very apt, though.

Didn't the deer just steal cancer genes or something rather than continuing to have... the same exact cancer in it? I'd think an actual bone cancer would likely spread more spherically, and considering it's made of bone itself it may cause other unforeseen damages.

Do its bone-tumor-antlers grow velvet like actual deer antlers? If so, how would they remove it? And if not, how would the exposed, living bone be protected from the environment?

The antler things are covered in skin and fur. The main thing is that they're unpleasant to bite into.

What keeps the perpetual bone cancer from metastasizing and spreading? Do they simply live such short lives anyway that the cancer's rate of growth and spreading isn't enough to interfere with their survival to reproduction and reproductive ability? Are these pieces of bone cancer actually benign tumors, at least until they've had plenty of time to reproduce? Is there something special about the chemical setup or epigenetics of the neural spines that makes the cancer only grow upwards?

It's interesting to see how the perpetually warm environment of obsiditree forests can be exploited for de-regulated endothermy.

Really liking this furball’s colors!

I'm getting a real opossum vibe from this (North American one), and I'm loving the design of the horns on the back.
