Serval by freckle-sized dots. "F. servalina" was first described in 1839 by Irish naturalist William Ogilby from Sierra Leone; in 1867, British zoologist John Edward Gray described "F. herschelii" from an Indian skin, which was probably the same as the servaline cat. In 1907, British zoologist Reginald Innes Pocock commented that the two forms should be considered independent species, but reverted from this in 1917. Eventually, the two forms came to be recognised as the same species. Another form, "F. himalayanus" (Himalayan serval), was described from a skin procured from the Himalayan region; however, Scottish naturalist William Jardine noted in 1843

Zoologist Jonathan Kingdon described the behaviour of a female serval in oestrus in his 1997 book "East African Mammals". He noted that she would roam restlessly, spray urine frequently holding her vibrating tail in a vertical manner, rub her head near the place she has marked, salivate continuously, give out sharp and short "miaow"s that can be heard for quite a distance, and rub her mouth and cheeks against
