This non-profit is working to prove that homeless people deserve healthy, happy pets. Homeless people have pets for many of the same reasons that people with secure housing do: for companionship, for protection, for their children to play with. (About 216,000 of the homeless people sleeping on the streets are with their families, according to HUD.) Largely, the pets are longtime companions that have joined their owners in the growing ranks of the newly homeless, holdovers from a time when both had secure housing.
