I actually didn’t have super high hopes for this hideaway. It was so inexpensive that it was more of a second thought to fill up my order. I’m so glad I bought it! It was smaller than I anticipated but it actually works out perfectly for her size. She’s a full grown, average sized Syrian. This would work just fine for most sized Syrians or dwarfs. I ended up digging up some bedding and burying half of it under bedding up until the little window and that half is open. She loves it and has burrowed in and made a tunnel through the other side of the tunnel into more bedding. I love the tunnel for her, but I almost never see her anymore! She loves it that much!
