Review on Hey-brother Cat Tree: Multi-Level Condo with Sisal Scratching Posts, Plush Condos, and Big Perches by Heidi Wilson

I have two large cats - one 13 pounds, one 16 pounds. Assembly took about 30 minutes to sit down and do. I put together a cat tower using only diagrams and photos. It wasn't difficult, you just had to pay attention to the different lengths of the supplied screws. You use the included hex key to pull everything together. Each part is physically marked with a letter and number and then basically step by step. It became an instant hit with both my boys. Both have ample stretching space on the top level and fit two suitcases very comfortably. They haven't tried sitting in the round part of the basket yet, but the perimeter is also big enough to hold them if they want to climb in. The tower seems solid and weighs 35-40 pounds I think. They've jumped on it a few times and it barely wobbles (although it's against a wall on one side) - I don't think I need to worry about it tipping over, but there is a strap to attach it to can the wall. so it doesn't fall over when I'm worried. The poles are designed so that you can replace/flip them with new sisal if your cats are wearing the original sisal due to their claws. The dimensions also correspond to what this online description says.
