A Maine Coon can live indoors, provided the home meets its needs and the arrangement suits the individual. Being large does not automatically mean needing a huge house, but the cat needs meaningful space to move, rest, scratch and explore. Think about the layout and daily routine, not just the floor area. An indoor lifestyle also makes you responsible for providing variety and opportunities for normal behaviour. Comfortable lookout spots, hiding places and interactive play can all contribute.
Avoid expecting one elaborate tree to supply everything. If the cat previously had outdoor access, a transition indoors may require extra planning and professional advice. Watch how your cat uses the environment over time and change unhelpful arrangements. A successful indoor home is one the cat can navigate and enjoy, rather than simply a place where the doors remain closed. Walk through a day from the cat's perspective: where can it watch quietly, stretch, hide, play and reach resources without being disturbed?
