The Assisi Animal Foundation is the first built no-kill, non-profit animal shelter in McHenry County. Our mission since our founding in 1983 has been dedicated to providing shelter, care and, where appropriate, re-homing animals to loving, permanent homes. We abide by a no-kill policy, which allows for euthanasia only under professional veterinary assessment in cases of terminal illness, injury too severe to repair, or severe aggression.

Located in rural Crystal Lake, Illinois, the acreage includes two pet buildings, an office, and specially designed Catios where cats have access to outdoor sights, sounds and smells in a sheltered safe environment. The AAF is dedicated to educating the public on animal welfare, providing a pet therapy program to nursing centers, supporting trap-neuter-return programs, and teaching humane attitudes and responsible pet guardianship.
