Task: Sentiment Analysis
Input (English): I purchased three of these for my cats. They were not cheap. Even the one that worked wasn't sturdy enough to stay on a regular carpet even when cats would jump on top and roll around. A total waste of money. What would have been great is if it worked. Update! This item totally fell apart less than 2 months after purchase. At first, no cat tried climbing up. Eventually they did climb up it. Unfortunately, one came loose from under a kitten who was playing with me.
Output (English): Bad review
