H.A.R.T. is a non profit organization registered with the IRS as a 501(c)(3) status #800726587 and also with the State of Arizona as a not-for-profit charity. Our mission is to engage in activities that curb overpopulation, impede the feral cat cycle, re-home abandoned cats and kittens, promote responsible pet ownership, and end the cycle of animal suffering by a humane approach that utilizes spaying and neutering as its primary weapon. We accomplish this goal by implementing feral cat management through the Trap, Neuter & Return program (TNR).
