This 44-in cat tower stands on an 18 by 13.5-in base, narrow enough to slide between a bookcase and a wall or into a studio corner. The 2-door condo at mid-height lets a cat enter one side and leave by the other, so no animal gets cornered by a housemate. Above it a plush hammock sways under weight, and a padded 14-in top perch gives a full-grown cat room to lie flat. Sisal-wrapped columns run between the levels for clawing, two balls hang low enough for kittens to reach, and an anti-tipping device ties the 20-lb frame to the wall.
