How to make a simple cat shelter out of a cooler

I needed a warm place for my outdoor kitty to sleep, but I didn't love what I found on Amazon - they were either overpriced or looked flimsy. It occurred to me that a cheap, insulated cooler would do the trick. I added a small heating pad made specifically for pets and she is happy as can be! Let me know if you found this helpful! Here are the materials I used: Cooler: https://www.walmart.com/ip/Igloo-48-Q... Pet-specific heating pad: https://www.amazon.com/dp/B001AZSR68?...
