Back again for some fennec fox recommendations
Lizard foxesThey could vary from iguanas with spikes running down their backs, leopard geckos with fat tails, day geckos with some outstanding colors and scales
frog foxesFoxes colored like various frogs such as
poison dart frogs, red eye tree frogs, glass frogs, pacman frogs, fire bellied toad and even throw in an American toad. You could also change the tails to something similar to a tadpole's tail
dragon foxesFoxes with wings and scales, and spines going down their backs. Even throw in some horns.
japanese kitsune masked foxesAs a big fan of Japanese culture I think this would be great! Put some kitsune masks on them and the whole litter could look similar, only difference is the mask and the markings. All white foxes with red swirls and other markings.
