This is an ice pillow for cats who don't like air conditioning. It uses ice packs that you probably already have in your refrigerator, so you don't need to buy special ones. It has a quilted core inside to retain heat and prevent it from getting too cold. With three ice packs (as shown in the fifth image), the coolness lasts for about 4 hours. (Adjust the number of ice packs depending on their size. The ice packs in the image are not included.) Also useful for preventing heatstroke during travel in pet carriers or pet carts. Stylish Nordic circle pattern. You can change the color to blue (as shown in the 10th image), so please comment before purchasing. *It may take a few days to ship. ⚠️ Please do not use the Mercari bulk purchase feature. Made of fabric Approximately 21.5 cm long, 15.5 cm wide Filling: Polyester *Ice packs are not included. Insert the required number of frozen ice packs and fold the lid under the ice packs. Handle gently, as the ice packs may come out if you turn it upside down or shake it. It lasts longer if you put in several smaller ice packs rather than one large one. (According to Ukiko-ya) We recommend drying it frequently to prevent mold. When washing, gently hand wash and dry well in a well-ventilated area after dehydration. Putting clothespins in the opening will help it dry smoothly. Do not use a dryer. It is difficult to put the inner bag back in, so please dry it without taking it out. When not using it as an ice pillow, you can use it as a regular pillow by putting in a hand towel.
