It is a he and he carries the name Xiao Pang Pang because of his huge tummy. Almost too hard to differentiate between her and Xiao Fei Fei, only that he has a strange long thin antenna-like tail and he is a HE. For your information, both of them keep playing wrestling all day all night.

His female sibling is also up for adoption, click on the link here, http://www.petfinder.my/pets/25784/
It is best that you could adopt both of them together.

Do kindly contact me via PM.
