Made with cotton sheeting fabric. The yarn core makes it soft and lightweight. I think it will reduce stress. ✔️ Slide the knots on both sides to widen the collar. Put it over the face, then adjust it to the appropriate size. You can wear it without untying the knots. ✔️ Consider the size of the face and the possibility of the collar getting caught, and choose the size that will come off easily if it does. ＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝ ❁ If you are unsure about choosing a size ❁ Measure the nude size while your pet is sitting. (= The perfect size without any extra space) The appropriate size is about 3-5cm larger than that size. The guideline is that you should be able to fit 2-3 human fingers in the gap. For kittens, about 2-3cm. It's best if you can fit 1-2 fingers in. This is just a guideline, so please use it as a reference. ❁ To keep it clean ❁ Wipe gently with a pet shampoo towel, etc., to keep it clean. ❁ The photo shows the smallest size ʕ•ᴥ•ʔ
