Sandpit at a good price
I use the sand house for my hamster and never had any issues with sand leaking out, but now I’ve filled it with corn granules. He loves digging around in it.
The fact that there’s no instructions included is a bit annoying, to be honest. I just looked at the product photo here and took five minutes to put it together calmly. It’s pretty self-explanatory, since everything fits together quite snugly—so if you notice any big gaps, something’s not right.
