both my girls get along fine and nether one of them are fixed. My bunny was almost a yr old when I got my bella. Bunny took to her right away. She dose not care to much about sharing mommy at 1st but now she has some one to take treats from....So now she can eat hers and then take Bellas 
 
  
Bella is now 1 and Bunny is 2 and there best of friends... Well minus the whole sharing thing... but what sis share anything, any how...RIght?
