I am not sure if anyone has shared the miracle nipple but they are great for orphaned kittens. They are more like a mothers nipple and kittens latch on more easily and it's better than the kind you have to puncture holes in. I found that the regular nipples you puncture holes in can aspirate kittens and this new nipple doesn't. You can google Miracle Nipple and it should send you to Henrys Pets. You will want to order the mini nipple not the regular size ones for those are larger but useful for force feeding. This nipple was very helpful to me this kitten season. I highly recommend them and so do many shelters.
