Advocates say wild horse is endangered species. In this June 5, 2013 photo, some of the hundreds of mustangs the U.S. Bureau of Land Management removed from federal rangeland peer at visitors at the BLM's Palomino Valley holding facility about 20 miles north of Reno in Palomino Valley, Nev.
To be more specific, the Serval is one of the few spotted cats not on the endangered species list. The formal biological description of the Serval would be: FAMILY:-felidae, ORDER:-carnivora, SPECIES-felis (leptailurus) serval.
For example, the cats produced directly from a Serval/domestic cat cross are called the F1 generation. F1 generation Savannah kittens are very difficult to produce, due to the difference in gestation periods between the Serval and a domestic cat (75 days for a Serval and 65 days for a domestic cat), and sex chromosomes. Pregnancies are often absorbed or aborted, or kittens are born prematurely.
