This 36-in cat tree gives kittens and smaller adult cats a full climbing route inside a footprint of just 15.5 by 15.5 in, so it slots into a corner, a bedroom, or an apartment living room without crowding the floor. A round plush perch sits on top for napping and window watching, while the enclosed condo underneath stays dark and quiet for cats that hide when guests arrive. Sisal-wrapped posts pull claws away from sofa arms, and a hanging rope, a dangling plush ball, and a spring-mounted ball keep solo cats busy between naps.
