Can a simple sentence have compound subject?

Here's the breakdown:

* Simple sentence: Contains one independent clause (a complete thought).

* Compound subject: Two or more subjects joined by a coordinating conjunction (like "and," "or," "but") that share the same verb.

Example:

* "Dogs and cats are popular pets."

Here, "dogs" and "cats" are the compound subject, joined by "and," sharing the verb "are." This sentence is still simple because it has only one independent clause.
