Cross Breeding Species List...

[Tam'ra of Rainbow Vortex]

There's some cats who can cross too:

The Ashera is now the world's most expensive cat breed at $22,000 apiece. This specially-bred cat is the largest, rarest and most exotic domestic cat in the world. It is a result of breeding the African Surval and the Asian Leopard cat with a domestic cat. It stands more than 1m tall (3.3feet) on their hind legs and grow to a top weight of 30lb - the size of a small dog.

I believe they are fertile.

Wolf and coyote can and have crossed, Eastern coyote DNA studies prove this. Offspring are fertile and are, according to current theory, still considered to be coyote because that is the dominant percentage of genes. Wolves have been eradicated from this portion of the US, supposedly. Way to go idiot humans
