What can cause a cat to lose its voice? Or make it higher pitched/squeaky?

This started happening to one of my cats last night. She’s an adult cat, but her meow sounded like a kitten’s meow in pitch. Today, her meow is really squeaky, high pitched, and incomplete – like it cuts out.

She doesn’t have a fever, she has no difficulty breathing, her nose is cold and wet, and she hasn’t been behaving weirdly.

Could she be getting a kitty cold? Is something possibly stuck in her throat? Should I take her into the vet or give it another day? (She’s an indoor/outdoor kitty.)
