You can initially leave cabinet doors open if the design permits this safely and the doors can stay in a secure position without swinging into the cat or obstructing the room. Check the manufacturer's guidance rather than removing structural parts or altering hinges without approval. An open front can make the interior easier to inspect and less enclosed during introduction, but it should not be used to compensate permanently for an entrance that is too small.
Keep the tray stable and ensure the cat's usual route remains clear. If the cat uses the open arrangement, make any later change gradually and continue observing its response. Do not close the doors while the cat is inside to test acceptance. If the setup only works when completely open, reconsider whether the enclosed version suits that cat. Its comfort and reliable access matter more than achieving the cabinet's intended visual appearance immediately.
Distinguish the large service doors from the cat’s intended entrance. Opening service doors can change the sense of enclosure, but it cannot establish that the smaller everyday passage will be comfortable once the cabinet is closed.
