Cats Anonymous, Founders
Cats Anonymous, Founders
Empathy and care brought our founders together in 2005 to establish a compassionate and highly effective solution to the growing concern expressed by communities across the region over the wellbeing of feral cats, the overpopulation pressure on shelters, and conflicts in neighborhoods.

By working with a network of veterinarians across the region we’ve built a leading Trap Neuter Vaccinate and Release (TNVR) program, and together we’re successfully curbing the growth of feral cat populations across Northeastern Wisconsin. We actively recruit volunteers to become colony caretakers. They provide in-the-field support for colonies and monitor current populations in their areas.

We work with local governments to make policy changes that embrace and develop humane solutions to address problem populations and to strongly encourage pet owners to become part of the solution by spaying or neutering their pets.

If you are a pet owner you can make a significant impact by accepting the responsibility to spay or neuter your pets. Unsupervised outdoor activity of pets is often the cause of feral population growth due to unknown and unwanted births.

Together we can humanely solve the conflicts communities have with feral cats and reduce the overwhelming intake of unwanted kittens in shelters. Our team of licensed veterinarians, veterinary technicians, volunteers and colony caretakers in the field are already improving the overall health and wellbeing of feral cat populations across Northeastern Wisconsin.
