My cat has developed raised black spots on his chin. What are these? He began with just one spot about two weeks ago, but now there are four.

It sounds like your cat may have a common ailment known as "feline acne." This condition is often treated with a topical cream or shampoo prescribed by a veterinarian. Using stainless steel, ceramic or glass food and water bowls is also recommended, as plastic bowls may be harder to keep really clean and, thus, may contribute to the problem.

There are certainly other skin disorders - some that are potentially serious - that mimic the signs you describe, so it’s important to consult your veterinarian and have your cat examined.
