Here we have the litter of Kitubron the marbled polecat and Sarlarma the Javan rhino, who mated here: https://www.sofurry.com/view/1570201

Balom: Male Miniature Javan Rhino with Kitubron's Marbled Polecat coloring
Manai: Male Polecat/Rhino Hybrid with blended colors from parents
Brana: Female giant Marbled Polecat with colors from both parents

Note: Rhinos are very sparsely haired, so their coloring is actually their skin coloring. For simplicity's sake, I'd like to assume that the skin color and hair color are the same in my world, even though I am quite aware that skin and hair color are likely different.
