I took a leisure walk into the wood today and found 2 distinctive different types of caterpillars, both species were found on two oak trees. Then upon returning home, I found another colony of cats. on my Red Buds tree. Could you help me I.D. these 3 species? One of the 3 looks very much like Datana contracta as mentioned by kwanjin, many thanks kwanjin.

First unknown, this one is a large cat. thinner than the typical sphinx moth cat. or Spicebush cat. But long, roughly 2.5" or more.
