However there is no full agreement among Vedic astrologers as to the gender related to a Nakshatra.

These animals are considered inimical to each other:

1. Cat (Ashlesha and Punarvasu) and Rat (Magha and Purva Phalguni)
2. Cow (Uttara Phalguni and Uttra Bhadrapada) and Tiger( Vishakha and Chitra)
3. Serpent (Rohini and Mrigshira) and Mongoose( Uttara Ashadha)
4. Horse ( Ashwini and Shatabhisha) and Buffalo (Swati and Hasta)
5. Dog (Mula and Ardra) and Hare (Jyeshtha and Anuradha)
6. Monkey (Purva Ashadha and Shravani) and Sheep (Pushya and Kritika)

Here are some tips:

• If the woman's Moon occupies a female Nakshatra and the male's Moon occupies a male Nakshatra and the respective animals are compatible, both are extremely compatible.

• If both partners have their respective Moons in Nakshatras that are both female and the respective animals are compatible, you are compatible.

• If the woman's Moon occupies a male Nakshatra and the male's Moon occupies a female Nakshatras and the respective animals are compatible, there is average compatibility. However, in case both Moons occupy a male Nakshatra, there may be some problems.
