"I got this for my cat, Jacques. My husband was complaining I was spending too much on things for our newly adopted family member, but Jacques didn't like the first scratching post we got him, so we needed a better one. He couldn't scratch the old one effectively because every time he dug his claws in, it would tip over on him when he'd drag his claws down. I got this one because the price was right, and I figured with the wide base, it wouldn't tip. (I didn't read the on-line reviews first. Oops!) At first, it was great, and Jacques just loved it, especially his "sun deck" on top. But then, he started taking these flying leaps to get on top of it, and the whole thing would tip over. I took some hand weights that are now too light for me, and I put them in the bottom chamber, so it doesn't tip over when he does that anymore. Unfortunately, he doesn't like going in the chamber now, but he loves the sun deck, and he loves the sissal scratching post in the middle. Overall, I think this thing is great, but I do wish it wouldn't tip over without the weights in the bottom so my cat could make the most of all the features of it."
