I have a collection of animal teeth too!! Teeny tiny puppy and kitten teeth...I keep them in a drawer of my jewelry box...my husband thinks I'm strange
glad I'm not alone!!
Oh I also have puppy teeth from our first dog, we picked her up the day after our honeymoon. I put them in a Christmas ornament which looked like a little metal purse that hinged open, so it's there but not obvious to anyone looking.
