The bad news is that at last count, over 70 million cats need rescuing. But according to at least one source—a major source in the scheme of things—the ASPCA—things are getting better. There’s no “handle” to be had on this yet—not by a long shot. There are still far too many homeless, struggling, and suffering cats (and dogs). But since 2011 the statistics are better.
For example, there’s a decline in the number of animals entering shelters. There’s a decline in the number of unwanted animals euthanized. There’s an increase in the number of lost pets returned to their owners. And there are estimated to be around 5,000 shelters throughout the nation helping.
Still, more people rescue their cats than buy them from breeders. There’s a larger 
percentage of dog owners who buy from breeders, however. And there are still more homeless animals than there are homeless people.
