Here's what we can deduce:
* Pelt refers to the skin of an animal, especially with the fur or hair still on it.
* Chest refers to the part of the body between the neck and the abdomen.
Considering these meanings, "pelt chest" could potentially refer to the furred area of a cat's chest.
However, without further context, it's difficult to give a definitive answer.
