I think the rings of hair, and hairless abdominal joints, and the diagonally forward facing hair around the head, make it more likely a Lasiocampidae. I hope you have it in protective custody to rear it to an adult moth for identification?
Just put it in a jam jar with some of its leaves. Very little struggle involved, less than for cockatiels for example, and more importantly very little is known about that caterpillar whereas the whole world knows about cockatiels. You could become world famous for discovering the first caterpillar of its species.
