Although small animals cannot speak, they have the same emotions as humans, and they will also feel sad when their friends die. When a foreign kitten saw the cat hair left behind by a deceased friend, it seemed to immediately recognize that it came from the friend's body, and immediately came forward to lick it and rub its face against it, which moved its owner very much.
The black cat Alesana and the tabby cat Sen are a pair of good friends who live under the same roof and are inseparable all day long. This carefree life only lasted until Alesana was 8 years old, when she was diagnosed with cancer and died last Christmas.

Their owner Emma Pearce didn't know how to tell Sen the news of Alesana's death, fearing that it would be severely shocked. Although the family never said it explicitly, Emma believed that Sen had already noticed that his friend had left. Emma said: "Since Alesana passed away, Sen would occasionally stare blankly out of the window for hours at a time. Except, he would sometimes stare blankly at the place where Alesana often sat."

Recently, the hospice company sent Alesana's ashes and a handful of hair to Emma's home. Emma then decided to put the tuft of hair in front of Sen so that he could remember his friend. When Sen saw the tuft of hair, he immediately began to lick it and rub his face against it, as if he recognized it from his friend Alesana at a glance. Emma had put this tuft of hair in front of Sen several times, and he did the same thing every time. Emma was surprised by Sen's quick response, but also very touched.

Emma is planning to wait until everyone in the family accepts Alesana's death, then she will frame the tuft of hair so that Alesana can always have a place in the family.
