There is no relevant scientific basis for the idea that the owner will be unlucky if the cat dies. If the cat is the owner's partner or family member, its death may have an emotional impact on the owner. Family members can feel very sad and lonely at the death of a cat.

As for how to dispose of the body, the owner can choose burial, cremation or other legal methods of disposal. No matter which method is chosen, the owner should arrange it as soon as possible to avoid the decay and odor of the body and to minimize the negative impact of the death of the cat on the family.
