I think Kevin should be evaluated by the vet. White mucous being produced while coughing could indicate respiratory infection or pneumonia, and if he is coughing a lot, then they can sometimes cause themselves to also vomit. The vet will do an exam and discuss the situation of his foster care and may recommend diagnostics like x-rays to determine what is going on.
