Very good - Recommended buy.
We have three cats which love to play wild. Think parkour against the walls, full WWE style flying wrestling, etc. We go through multiple tents every year, as they will divebomb onto them, or push them w/their paws. They may drag them into the garden, just as they are used throughout the garden all year, as a supplement to proper cat houses. They take massive beatings.
When the tents break, it is one of the stitching in the corners give in, in a corner, meaning they warp. Usually takes 2-3 month
