My black foster mom had 4 solid black shorthair kittens 3 days ago. They are way too small for collars. I need to tell them apart so I can track their weight. There is not one white hair or whisker to be seen. Any ideas?

In fact, they look a little bit better than Sharpies.Water, Acrylates, Copolymer, Propylene Glycol, Propylene Glycol Butyl Ether, Dipropylene Glycol Butyl Ether, Trimthyl Pentanyl Disobutyrate, Sodium PCA, Ammonium Hydroxide, Butoxyethanol, Alkylaryl Polyether, Simethicone, Glutaronite, Quinacridone Violet 19.
