Insulated outdoor feral cat Barn cat winter shelter with new straw. Outside dimensions are 27.25 long x 14 wide x 12.5 tall. Inside dimensions with the styrofoam are 25 long x 11.5 wide x 9.5 tall. It has a styrofoam lid.

I've made one of these shelters for a feral cat I've taken care of many years. She's been living in a covered window well with straw for years but now prefers this cooler shelter.

I do have one more of the same cooler I could make in to a shelter if you're interested
