This is my dog cage for a Nissan xtrail any model up to 2014 shape change I think I had it for my Nissan xtrail 2003 but have just put it in a 2013 model and it fitted also. It’s a hamster basket dog pod made form light wire coated with plastic. The central divider can be removed to make 1 large cage and it has 2 doors. The divider can be moved to have one side smaller than the other or as it is with them pretty much the same. It also splits into 2 so you can have half the cage in the car if you wanted to. It’s not in perfect condition a bit bent in a couple of places but perfectly usable and safe if you want a cheap solution for the back of the car.
