Really good quality and seems like it will stand the test of time even with nibbly guinea pig teeth. Really spacious and will comfortably accommodate two guineas. You can attach a sipper bottle and it has a little pouch at the side for spare food etc. I used it to introduce a new guinea and it worked perfect for the purpose of keeping the guineas separate but still being aware of each other. It's also ideal for when we go away for the weekend and take the pigs with us. Definitely recommend. Also delivered really quickly.
