On Earth, almost all sexual relationships are intraspecies (mainly because they can only reproduce with the same species)*.
However, Vulpes is different, All Vulpines have the same number of chromosomes as humans do (46), there are "mutations"
in a Vulpine's sex chromosomes that give them their animal traits and/or appearance, while keeping some of their human traits
(I.E. the ability to walk on 2 legs, speak human languages, etc.). Because of this, Vulpines are able to successfully
cross-breed with other species. There are three reasons why there are Interspecies Relationships on Vulpes, that will
be listed below.
1. Dependence on other species to reproduce
Certain species on Vulpes (I.E. Pandas, Wild Cats, Hedgehogs, as well as a few others) are female only. If one
of these females wants to reproduce, they have no choice but to choose a male from a different species to yiff with.
Usually (except in the case of Pandas and Wild Cats), these females will choose to yiff with males who are the closest match
to their species (I.E.: F Hamsters will most likely allow M Mice or Rabbits to yiff with them as opposed to other non-rodent
2. Family Planning
When a male (or female) wants to have a large family in a fairly short amount of time, they will usually cross-breed
with high fertility partners (usually Mice or Rabbits). This can also work the other way, for couples who want families
but don't want large families (in these cases, Pandas, Does and Humans are best).
3. The Joy of Yiff
In some cases, males and females of different species have a strong natural urge to yiff. For instance, on Earth,
to a male fox a female rabbit would equal "fast food". However, on Vulpes, that same natural urge has been converted
to a safer (for the rabbit, anyway) instinct. The human traits of the male fox would convert the natural instinct to
kill and eat rabbits into a natural instinct to yiff with female rabbits. Also, since not all Vulpines are the same,
certain species may have things that other species do not have. The strongest example of this is the canine knot, the
vast majority of all females on Vulpes can be tied by a male fox (or other canine male). These females already know
that when a canine male ties his mate, it is the strongest example of showing his love for his mate (the longer the tie lasts
the more he loves his mate). Many females are curious to feel the canine knot inside them and to be tied by a canine
At the top of this page, there is a "Top 10" table of Interspecies Relationships. This is based on three things...frequency
of relationships on Vulpes, mutual pleasure, and origin of that particular pairing.
