They are so much fun and a very unique pet! We had 2 ferrets about 13 years ago. Definitely need to multi-level cage and a hammock to sleep in. If they are out you have to watch them like a hawk! When we were moving, we found so much stuff underneath our dresser!! They are little theives.
Don't know if you remember the '80 something movie "Beast Master" the two ferrets were Podo and Odo (I think?) thats where I fell in love with ferrets. BUT the "fragrance" they put off was eventually too much. No matter how much you bathe them - they will have that musty odor. Anyway, nothing compares to my Yorkie Babies!!
