Neither source explains how to switch cats in the current game. The cat discussion reviewed for this page is about behavior, carrying and feature requests; it does not show a selection menu. This page therefore states no wardrobe, bed, shop or interaction prompt.

Still to confirm: whether changing cats is available without DLC, where the selector appears, whether a bed or adoption quest is required, whether the choice can be reversed, and what happens to the existing cat. Until then, use this page as an evidence boundary rather than a step-by-step guide.
