Re: Pet barrier for behind front row seats...
I have this one from Amazon. It attaches to the headrest posts in the back seat. I had it in the Outback and it also works great in the Grand Cherokee. Although I have only used it on the back seats, the photo shows it being used on front headrests. You would still have the opening by the console unless you have some other barrier.
