Sourdough Starter Warmer Mat, Precise 1°F Thermostat Control (70-100°F) Sourdough Starter Warme Mat, Warmer for Sourdough Starter, 0-24h Timer, Auto On/Off, Memory Function (White)

I bought this specifically to keep small Fancy Feast cans warm, and it does that perfectly with steady, gentle heat that never gets too hot or risky. I like to feed my cats warm food. Cold pate just seems unpleasant. As a bonus, it also works better than any coffee cup warmer I've tried, warming flat‑bottom mugs and containers with real, consistent heat instead of the usual lukewarm shrug. It's a simple, reliable low‑heat slab that quietly does exactly what you want. I recommend saving the instructions as the controls can seem confusing at first glance. It's nice looking, take up a small space. It has a lot more uses than sourdough starter. I don't make bread, and was using a wax warmer to heat cans but got tired of having that bulb on all night. This is perfect.
