Direct answer: cats sharing a home need multiple, separated resources because one cat can block or discourage another without an obvious fight. Duplicating items in one corner does not create genuine choice.
List the resources that matter
Include food, water, litter trays, beds, hiding places, scratching surfaces, play and elevated rest. Start with one per cat plus extras where welfare guidance recommends it, then observe actual use.
Spread access across routes
Avoid placing every desirable item in a single room or narrow corridor. Give timid, older or less agile cats options that do not require passing the other cat.
Watch quiet signs of competition
Waiting at doorways, leaving when another cat arrives, toileting changes and loss of access to favourite places all matter. Sudden behaviour changes should also be discussed with a vet.
