The Plastic Tray is a great option if you are not going to use the functional cardboard box. The tray is designed to accommodate the Fresh Patch Large grass pad (24" x 24"). The grass is easily removed from the cardboard box and inserted in the plastic tray.
The tray is helpful if:
1. Your dog chews on the cardboard box
2. Your Fresh Patch is being used outdoors in rain or snow
3. Your dog needs a lower profile for entrance into the unit
This purchase exceeded my expectations
My small dog is more than happy to use it on cold days on our balcony, rather than go out on to the cold city streets.
We bought the large patch with the plastic tray and it is absolutely perfect for our 2 small dogs to use on our high rise patio. It recently snowed and our pups were so thrilled to have a snowfree space to do their business.
I was leaving the grass in the box it came in, but it leaked. This plastic tray works great! When the new grass comes, we take it out of the tray and put it in the old box with lid for trash! I recommend the tray.
