Trying to separate and just wanted to make sure these are all cat eyes. TIA

Best books? Apps? Any information that is helpful accurate and informative on marbles and how to tell what is handmade/rare etc.
trying to restart collecting.

Someone brought me this massive box of these and I just do not recognize them. I let my kids open a couple and they are kinda strange.
Any help is appreciated! TIA
