Animal shelters already care for and try to find homes for untold thousands of lost, injured and abandoned cats, in addition to pet cats whose owners are unable or unwilling to keep them. Because feral cats are so scared of people and usually cannot be adopted, those who are brought to a shelter, especially cats who cannot be identified as members of a known TNR-ed colony, are likely to be euthanized either right away or after a holding period. It's a complicated situation: While it's difficult to accurately identify a feral cat without observing them during a holding period, safely caring for a feral cat in a typical shelter cage is terribly stressful for the cat. In addition, if space is limited we may not be able to take on other cats.
