A message from Dr. David Duffy, Pacific Cooperative Studies Unit (PCSU), University of Hawaii (posted 05 November 2012):

Because of a lack of funds, HEAR (www.hear.org) may close as soon as December 15, although there may be enough funds to extend it until February 15. This will mean several things. The web site will be placed on a new server although it is not clear who will pay for the server or for transitioning the site. HEAR data will not be updated. The Pacific Ecosystems at Risk (PIER) (http://www.hear.org/pier/abtproj.htm) site will also become frozen, as will numerous books, reports and papers (http://www.hear.org/). As software evolves we will likely lose the ability to access the data. The various list servers will need new owners, otherwise moderated lists will cease to function altogether, while other lists will not be able to add or delete members. The photo collection (http://www.hear.org/starr/images/?o=plants) will remain accessible, but only through a third party site that will charge for access.

I should point out that we have already lost the original homes of both the Pacific Basin Information Node (PBIN) and Pacific Ecosystems at Risk (PIER) although they have found temporary refuges. Together with HEAR, they represent the corporate memory both here in Hawaii and across the Pacific of efforts to sustain our natural ecosystems and agriculture against problems caused by species alien to the islands. HEAR also serves as the glue that holds the community together, providing information and facilitating communication. I just hope hindsight is kind to this decision.

Species description or overview

Felis catus description and ecology from GISD (ISSG)
A species description and information about the ecology of Felis catus as an invasive species is provided from the Global Invasive Species Database (GISD). GISD was created and is maintained by IUCN's Invasive Species Specialist Group (ISSG).


Taxonomy & nomenclature

The Integrated Taxonomic Information System ITIS provides authoritative taxonomic information on Felis catus, as well as other plants, animals, fungi, and microbes of North America and the world.


Impacts

A day in the life of a traveling feline
This "KittyCam" study presents significant findings suggesting that suggesting that prey captures by free-roaming (outdoor) pet cats may be much more common than previously proposed. Though we already knew that domestic cats were generalist predators that may exploit a wide range of prey, the frequency of predation has been unclear and a point of contention in public debates, specifically with regards to responsible cat ownership. Researchers have previously studied predation by collecting information from homeowners on the type and frequency of prey that pet cats deposit at residences. That methodology, however, underestimates predation because cats do not bring all kills home. In fact, our study indicates that the majority of prey is eaten or abandoned at the capture site.

Predation by domestic cats in California, Florida, and Hawaii
Background: Domestic cat predation on wildlife is a serious conservation issue, particularly in California, Florida, and Hawaii. These states have: (1) sensitive ecosystems endangered by urban sprawl, especially in coastal areas; (2) the greatest numbers of threatened and endangered species in the U.S.; and (3) large numbers of free-roaming owned, stray, and feral domestic cats, partly due to warm climate allowing cats to breed year-round. This article contains general information on cat predation, as well as suggested activities for students.

"Cats Indoors!"
"Cats Indoors!", the Campaign for Safer Birds and Cats, was initiated by the American Bird Conservancy (ABC) to end the unnecessary suffering and death of birds and other wildlife caused by free-roaming domestic cats. Cats Indoors! seeks to educate cat owners, decision makers and the general public that free-roaming cats pose a significant risk to birds and other wildlife, suffer themselves, and pose a threat to human health. (excerpted from website)

Cats Indoors! information for veterinarians
American Bird Conservancy (ABC) has developed educational materials including the popular brochure Keeping Cats Indoors Isn't Just for the Birds, which explains in detail why cats should be kept indoors, and some simple suggestions on how to keep an indoor cat contented. The flyer, "Healthier, Safer: Indoors," gives tips on making an outdoor cat a happy indoor cat. You can order brochures and flyers to hand out at your practice, and download free resources such as a poster to display in your waiting room and numerous fact sheets.
