The first renter constraint is no permanent changes to walls or floors. Choose floor-standing, disassemblable cat trees over wall-mounted shelves that need drilling.

Window views can use suction-cup perches or no-nail brackets, but confirm load limits and window material, and recheck the suction cups regularly.

Choose movable litter boxes and feeding stations so a move does not force replacement because of size or installation.

Minimal gear does not mean fewer resources. Cats still need scratching, climbing and hiding spots, which boxes and furniture can cover temporarily.
