Retains heat for 1 to 4 hours, but cats avoid the smell.

The directions say most microwaves heat in 4 to 5 minutes. My microwave takes 7 min & 30 seconds. When fully heated it feels like there is warm / hot liquid inside. As it cools, it gets less squishy. When totally cool, it is back to being hard. I tested these in a Michigan winter. The weather outside has been in the single digits with a few days getting well below zero. Inside the house, the disc retains the liquid warmth for a good 3 hours, maybe 4. Outside, it retains heat for 1 to 2 hours, BUT that is when not wrapped in anything. I have been putting it under a bowl of wet food to slow the freezing of the wet food. It does help, but the smell keeps the cats away. I tried putting it inside a cat shelter, but again the smell repels the cats. It might work if u wrap it in a towel (as they advise) to dilute the smell,but then u also dilute the warmth. It’s not totally useless, but I haven’t found the best way to use it yet (w/o the smell repelling the cats).
