You may find that your cat chooses a different resting surface when the room becomes warmer. Offer suitable options rather than assuming they must continue using a deep or enclosed bed throughout the year. A flatter washable cushion or an accessible shaded resting place may be useful alongside the familiar bed. Check how direct sunlight moves across the room and ensure the cat can leave a warm spot freely. Do not place bedding where it blocks ventilation or against a heat source. If you remove layers, confirm that the remaining bed is still intended to be used that way and does not expose fasteners or unsuitable filling. Seasonal preference is different from signs of illness or heat-related distress; concerning changes need appropriate advice. The practical aim is choice and easy access, not making a cat remain in whichever bed matches the current season's marketing.
Keep a familiar warm bed available if it remains safely positioned, rather than removing every cosy option at once. Offering an alternative lets your cat choose between surfaces as the room's conditions change.
