I am currently waiting for my shelter to get rats in. Unfortunatly I will not be able to get a ferret nation due to my limited space and the huge pig cage. I was wondering if there is any other cages large enough. I plan on getting 2-4 ratties in the near future, maybe after Christmas or around then depending when the shelter gets in rats. I am still researching but any tips on diet or other things will be appriciated. Also do the males and females have many differences as far as personality.
