Solutions To Pet Abandonment, Overpopulation, & Overcrowding Of Animal Shelters

We’ve already written a guide outlining how we might decrease the rates of pet abandonment, overpopulation, and overcrowding of animal shelters.

Some interesting approaches and solutions that have already shown to work in real life scenarios are:


Pet Owner Support Programs

One example is the ASPCA launched a “Safety Net” program, and another example is the program run by the Animal Humane Society.

The Safety Net program for example has obtained data that up to 80% of the people they help end up keeping their pets in the short/early term [but there is no long term data we could find yet].

It’s been found in one survey that up to 80% of people are unaware of the resources out there to help support them and their pets, but up to 88% choose to pursue finding out about resources rather than going straight to surrendering their pet (


Pet Portals & Hotlines

RSPCA Queensland has a pet portal, and the Animal Human society has a pet helpline.

Both services help pet owners know their options when they are thinking of surrendering their pets.

Some results achieved from the pet portal are:

  • There has been 22% fewer surrenders from 2016-2017
  • Each pet that is surrendered to the RSPCA costs about $25/day to care for and the surrender portal have saved the RSPCA an estimated $800,000 in animal care costs
  • For every 9.59 views on the Surrender Portal, there was one pet owner that changed their mind about surrendering their pet
