I bought this beautiful fun trio Y shaped cat play tube for my cats birthday. They are brothers and turned 3 this year and are the sweetest most loveable good kitties an owner could ask for. I've bought them play tubes before but they could only use one at a time but this one is soooooo much more fun!! They go running through each tube chasing after one another and they love the hanging balls too. I have purchased from this brand before so I knew it would be high quality and made well. Thank you isYoung for making such high quality pet products. I highly recommend this brand and this tunnel.
