I'm excited by the idea of hybrid animals. It took so long just to get around to Legosi's minor traits and family. Also that in this world animals seem to have remained very traditional to their species, which s is surprising considering that it's not only is is hard to find the love of your life but also restricting yourself to the same family of animal at minimum.
I hope most hybrid animals to this degree are sane though, there is worrying implications even in complete fiction of 'hybrids' always being some psycho unstable creature...
