One of the bigger challenges one faces when drawing furries (those whose species don't have individual-to-individual unique markings anyway) is making sure two characters don't look the same. I (think) I've managed that here, and Karine's grandpa looks like neither a very old Theran, nor Karine in drag. :P

On the topic of cross-breeding; almost all of the furkin, scalekin and airkin races can interbreed. The resulting children can be anything from looking entirely like one parent's race (although with some minor genetic benefits or defects from the other), to looking like a mixture of the two anywhere along the scale between both species. Karine, as a second-generation descendent of the pairing of lion and fox, resembles her own father (who is more lion than fox) more than she does her grandmother.
