Open the full QuickStart
Before first use
Read the supplied instructions. K&H says to consult a veterinarian before use with young puppies or kittens, convalescent pets, animals in surgery recovery, or animals unable to move away voluntarily.
Manufacturer informationOfficial heating instructions
Follow the instructions supplied with the product. K&H says to microwave only to the point where the contents become liquid and warns against heating much longer than that point. No fixed duration is set here.
Manufacturer informationPlacement
Place the warmer inside the pet bed, with bedding or a cover between the warmer and your pet. Always leave enough space for the pet to move off the warmed area.
Manufacturer informationIndoor vs outdoor considerations
The product is designed for indoor use. K&H says outdoor cold causes warmth to diminish quickly, so do not treat it as guaranteed overnight outdoor heat.
Manufacturer informationWhat happens while cooling
Customers report that the contents become firmer as the warmer cools. K&H also notes that the small hard object at the top edge is the plug that keeps the inner material contained.
Verified buyer feedbackCare and cleaning
Hand wash in a sink with soapy water, rinse well and line dry.
Manufacturer informationCommon mistakes
Avoid direct contact, confined placement, relying on a fixed web timer instead of the supplied instructions, or assuming the indoor maximum applies outdoors.
