Does anyone out there know of a way to keep wet cat food unfrozen during these dastardly cold days? I'm feeding a colony of ferals, anywhere from 9 to 10 cats, and although I do have dry cat food out, during this weather I am trying to give them some additional nutrients to assist them. I'm usually pretty creative but I'm stumped. They do come up on my porch to eat and I was thinking about a heated water bowl to put the wet cat food in. Any ideas would be appreciated.
