The K&H Pet Products Snuggle-Up Bird Warmer is designed to help protect your exotic birds from the harmful effects of air conditioning and cold drafts.

Available in two sizes for any size bird…from cockatiels to African Greys to Macaws we’ve got you covered. Designed by K&H with OVER 20 years of experience in creating safe, innovative, quality products for pets; one-year limited warranty. NOTE: The 12V electrical current is harmless to your bird; but as with any electrical products, please keep the cord away from the reach of your bird to avoid damage to the product.
