Best rodent run out there
Got this for my year old Syrian hamster (called Riat) in January this year (2015), I wanted something sturdy and tall so that Riat wouldn't climb out.
This run does the job, it is more than tall enough and also very spacious so you can fit a fair few toys and climbing frames in there.
I myself have it connected to the hamsters cage with tubes so Riat can have constant access to the run.
However I will say this, if you place it on carpet don't be surprised when your rodent chews a hole in the carpet in the corner of the run! My advice would be to lay something underneath like a mat that isn't chewable.
This product is lightweight and fits together very easily.
Your rodents will appreciate the freedom and new space, and you won't have to worry about supervising your companion animal constantly but do make sure they have access to food and water if you plan to keep them in the run for a while.
