Kittens in California shelters may now be adopted before 8 weeks of age thanks to Assembly Bill 1565, which Governor Gavin Newsom signed into law over the summer. The bill also waives the former mandatory six-day waiting period required for stray cat adoption. The bill was backed by the San Diego Humane Society and the San Francisco Society for the Prevention of Cruelty to Animals, among others. Because of their immature immune systems, young kittens are more susceptible to picking up infections and communicable diseases. Quickly moving them out of a shelter environment to an adoptive home lessens the chances that they will become sick.
