Omaha Steaks shows feral cats love
I, and most of the animal rescue folks I know who do Trap-Neuter-Return for feral cats, often steal meat-packing coolers out of the trash. They are thick enough and small enough to double as winter feral cat shelters in a pinch once a 6"x6" door is carved out.
This envelope was left in the last cooler I picked up, with Omaha Steak's ideas for reuse and recycling -- imagine how surprised and elated I was that they included this suggestion for using coolers to provide much-needed shelter for feral cats braving the chilling winter.
