This hutch arrived earlier than expected. Super quick build (like 20 mins w my 9yr old niece helping). I used a drill but it's soft wood so if you haven't built these before beware as you might crack the wood. 

4.29.19 Updated review. Sadly in less than a year this hutch ended up being junk. It won't hold up with small animals as it's easily chewed up due to the cheap, soft wood used. Not too mention it is terrible to clean and I suggest you save your money and buy something more durable. The wood has chipped, broke, been chewed almost to where the cage is no longer secure for critters. It's going to the dump later today. =(

Id only recommend this hutch for guinea pigs as its not very tall. 

Overall Im satisfied with this purchase as this hutch is exactly as discribed.
