This comic strip was a bit painful to post. Only because in a furry world, hybrids never made much sense to me, unless they were of a similar genome. (i.e. Horses and Zebras for example.)
In which case, Cally is a wolfmouse, which does actually exist as its own species. Not a hybrid of a wolf and a mouse!
Even so, in a furry world, there can’t be a hybrid of a raccoon and a mouse, it would look strange. This undoubtedly leads to some tension between them as suddenly they’ve found out that a world event as caused a change in their family dynamic.
