Funny as it is. My cats kittens are all different stages and sizes though born same day. The biggest eyes are open. Ears erect starting to walk and worse is now teething. She's getting upset and leaves all the kittens when he trys to feed. But the rest are far to small to ween. The tinyest is barely able to do anything but cry when she's away. Can I try introducing it to wet food??? Then mix in formula
