  • Make sure your cat’s food is at room temperature.
  • When using a microwave set the temp to low. Microwaves work by causing water molecules in the food to vibrate, building up steam which causes the food to heat. Doing so leads to very hot and possibly overcooked spots while colder areas remain unheated. The result is a lukewarm meal at best.
  • If you’re adding wet food to dry, we recommend letting it sit for five minutes after microwaving and then stirring before serving. Letting it sit will allow the coldest parts of your cat’s dinner to reach room temperature, so you do not shock their system when served.
  • When heating wet food alone, be sure to warm it thoroughly. Cats can get very sick from eating partially frozen or cold food – so don’t take any chances!
  • If you wish for faster results, place the bag or can inside a pot of hot water for 5 or 10 minutes until the food reaches the ideal temperature. (especially good with dry cat food)
