A 2021 study by the American Pet Products Association found that some 12.6 million American households obtained a new dog, cat, or other pet during the COVID crisis's height in 2020; in turn, this created many opportunities for those who already liked working with animals. People who had long made their livings dealing with animals in one way or another were relieved when a majority of Americans got vaccinated for Covid-19. That contributed to a return to some degree of normalcy in many job markets.
