I now for sure that they are a girl and boy, and I have put them in each other's cages so they can smell the surroundings etc. Also yesterday i think she was 'ovulating' because she did have an odd smell so i tryed putting them together, and they did start sniffing eachother & grooming but then they started to roll aound and squeak ad to be honest I didnt notice any biting, so I wasnt sure if they were actually play fighting lol or just fighting - how can i tell? Pleasee Help Me Thanks (:
