Hayden Island offers a unique opportunity to study humane solutions to cat overpopulation. 

With strict geographical boundaries of the Columbia River banks and home to hundreds of feral/stray and abandoned cats, Hayden Island provides a natural opportunity to scientifically investigate and apply innovative methods to humanely reduce the island’s feral cat population.


Get Involved

Volunteers conduct physical counts of free-roaming cats to determine how many live on Hayden Island. Mark your calendar! Our 2018 count will be held on September 9th, 23rd & 30th. Want to join us? Email Joe Liebezeit.

Increase TNR

After establishing the initial baseline population estimate in fall 2014, Trap-Neuter-Return (TNR) efforts have been increased in cooperation with island residents. We're here to help! You can help, too. Spread the word with the information below.

Support Cat Care

We work with the Hayden Island community to assist in the management and care of free-roaming cats. Efforts include offering spay/neuter specials for local cats, partnering with feral cat caregivers and residents to monitor cats, finding homes for socialized feral cats, and increasing awareness of cat, bird, wildlife and habitat welfare.
