Therefore, after considering a case that is as small as possible and made of a soft material that won't burden the cat, this design was created. By attaching the AirTag to the collar, you can use your iPhone to find your cat's location. You can also make the AirTag emit a sound to pinpoint the location. Please refer to the AirTag manual for instructions on how to use the AirTag. The photos have not been adjusted or processed for the size of the case. My cats have been using it without any problems. ◉ This is handmade, so it is not a perfect finish like a mass-produced product. While it is made to be safe for use, there may be slight imperfections such as uneven stitching or misalignment of fabric layers. Please understand these points before purchasing. ◉ It will be shipped by regular mail. Please note that delivery times seem to have increased since Saturday deliveries were discontinued.
