yeah
A vestigial structure is a structure that an organism still has but no longer serves any real definite purpose. In this case, the whiskers on a cat serve a vital purpose, so they are not vestigial structures.

Vestigial structures are considered evidence, but no more critical than any other line of evidence in Biology and palaeontology. They're considered evidence, not because of their function, but because of the way their morphologies follow the nested hierarchies of biology: the vestigial legs of whales, for instance, have exactly the kind of shape we would have expected them to have if whales had descended from land mammals. The same goes for human tailbones and embryonic branchial ridges, the wings of emus, and so on.
a. the presence of homologous structures b. the presence of vestigial organs
The existence of vestigial structures is significant to the study of evolution because they provide evidence of an organism's ancestral lineage and indicate how species have adapted over time. These structures, which have lost their original function, suggest that evolutionary processes lead to changes in anatomy and functionality in response to environmental pressures. By studying these remnants, scientists can trace evolutionary paths and better understand the mechanisms of natural selection and adaptation. Overall, vestigial structures highlight the dynamic nature of evolution and the relationship between different species.
Vestigial StructureA vestigial structure is a structure that appears to no longer have a use in the body.
No, because the use now would be the use then which is not really vestigial.
They don't, vestigial structures are biological structures with no known function that evolved from structures in distant ancestors that used to have a function that is no longer needed.

vestigial
Humans: the appendix, wisdom teeth, and ear muscles are examples of vestigial structures. Whales: hip bones and hind limb remnants are vestigial structures in whales. Pythons: pelvic spurs, remnants of hind limbs, are vestigial structures in pythons.

Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
Tailbones, tonsils, appendix,
Yes you just did
vestigial structures.
