Complete indoor living is the best way to keep cats safe, but without the stimulation of going outside, you need to enrich the indoor environment to meet your cat's physical and mental needs. Insufficient enrichment (environmental enrichment) can cause cats to develop problem behaviors such as excessive grooming, furniture destruction, overeating, and aggression.
Understanding Your Cat's Instinctual Needs
Cats evolved as solitary hunters. Indoor cats still retain the following instinctual needs.
Hunting drive: Cats conduct 10-20 short hunts per day, catching and eating small prey. In pet cats, this drive must be satisfied through play.
Territory patrol: Cats regularly patrol their territory to check for safety. Ideally, an indoor cat should be able to freely move between multiple rooms.
High-ground surveillance: Cats gain a sense of security by observing their surroundings from high places. High places serve as safe resting spots and positions of dominance.
Scratching: A natural behavior that serves both marking purposes (visual and olfactory) and nail maintenance. Without appropriate scratching posts, cats will use furniture instead.
Hiding: Cats feel safe hiding in enclosed, narrow spaces when stressed or resting.
Setting Up Vertical Space
For cats, vertical space is just as important as horizontal floor area.
Cat trees: Install at least one cat tree that's 150cm or taller. Ceiling-tension types are highly stable and safe even for large cats. Step spacing of around 30cm is ideal, as it's easier for senior cats to climb. A bed or hammock on the top tier allows cats to lounge for extended periods.
Cat walks: Installing shelves on walls to create cat walks turns the upper part of the room into a cat pathway. Designing routes that go through window areas or over bookshelves allows cats to enjoy patrolling while moving around. Applying carpet or cork to shelf surfaces provides traction.
