Heated Sidewalk Mats...hear me out!!

[DoodlesDuckies]

I am located in Central WI and it gets COLD...like -20 F COLD. What if I would run one of these heated walk mats (they are on Amazon) to keep a small area kinda sorta thawed. I do have 2 heated dog bowls that did AMAZING during the -35 F temps we had earlier this week. I found these heated mats and thought HEY...I know a few birds that may appreciate something like this.

I thought about maybe putting turf over the mats or even landscaping fabric and change it out off and on.

Thoughts?
