text: Just right for mice and dolls....
  
  Yeah, that's about it. The nipple pieces are so tiny that at best, they are fit for feeding baby mice or maybe baby gerbils. I can't use them for my two little, five week old puppies. They weigh 1.3 and 1.5 pounds respectively, and this teensy nipple is too small that they would even recognize this as something from which to suckle. Other use I can think of for these would be a 5 - 10 year old girl, who wants to bottle feed her dolls. She would love these! I can't imagine how the makers can claim that all professional nurses use them for new born animals. I don't believe it! I am going to buy some real baby bottles with some real nipples.
