Go buy it if your thinking about it seriously!! I have a 60 lbs pitbull mix and she is super hyperactive and high energy. We have a black large KONG cage and it’s an absolute eye sore to the entire house. We live in a apartment and the KONG cage really made the place look cluttered. We ordered a XL and she has a lot of room in it to lay down and stand. We could have definitely gotten away with a large but I’m happy with the purchase. Also I’m 113 lbs small skinny mom and I built  this alone with no help plus two toddlers running around and a baby. Don’t be scared of all the pieaces. Just follow the instructions step by step and you’ll be fine.
