Are you sure? Many diseases cross over from animals, including some famous recent examples...
Or to put it another way, animal diseases are just a step removed from the anthropic filter: if there were more extremely fatal animal diseases, then because they often cross over to humans...
Some species don’t easily cross-over to humans, and in fact most diseases don’t easily cross-over (influenza and SIV are major exceptions but the pattern is that cross-over is itself pretty rare). We could maybe look at species which don’t cross-over to humans due to much different biology, like say in cephalopods. I’m not sure we know enough about disease in such species though, or that they are similar enough to mammals to be a useful comparison.

There’s plenty that don’t cross to huamns.
I don’t think there’s any shortage of data unmuddied by anthropic bais.
