Hi, Have to tell you about our hit rate. It used to zero, zip, zitch, nil, nada. I have 1 boy & 1 girl. I asked for some advice from a very smart ferret person - Bev Fox (North Coast Ferret Shelter) She told me to change the kind of litter box to a small cat box - can be purchased at Wal-Mart for $1.99, & since then (I,m telling the truth) we have had a 100% hit rate. Thank you Bev!!!! It may work for you too, it may not, but for $1.99 - what do you got to lose? Also, can anybody tell me where I can get designs, material list, ect. for making my own cage. My fuzzies want more room & they told me that they want ferret math to hit their house soon. Would like to make a two or three story house. I,ll take any info you have.
