Sorry, I half misunderstood your post & half just warning. You are a responsible owner therefore understand that there are a ton of people out there that are not. Unfortunatlly I do not have magical powers yet to determine who is & who is not a great pet owner LOL. Therefore to be on the safe side I like to inform people as much as possible. Others were reading this post too so it may be helpful to them well.
Sorry all your encounters w/ ferts have been bitey. They are quite nippy when kits (just like pups) & if raised improperly, my gang is so sweet & kind. They really are great pets.
