Five different places to sleep stack up this 58-in tower: two condos with wide entrances, a large open basket, a slung hammock, and an upholstered top perch. Cats rarely stay loyal to one spot, and this range covers an animal that wants walls in the morning and open air by afternoon. Wide jumping platforms bridge the levels, several scratching posts run between them, and hanging balls sit low enough for a kitten to reach. Thickened wooden boards and a wide 24 by 18.5-in base carry the 40-lb frame.
