There is a worldwide demand for more humane devices to capture animals, both fur bearers and predators. This demand arises for both environmental and ethical reasons. An Agreement on International Humane Trapping Standards signed in 1995 by the European Economic Community, Canada, and Russia may ultimately lead to the banning of all steel leghold traps in those countries. Already some states in the U. S. (e.g., California, Colorado, Washington, Massachusetts, Florida, and New Jersey) ban these traps.
The trigger requires a pull action rather than the push/depress mechanism normally employed by traps. The effectiveness of this action for canine specificity has been proven through the years by the M-44 cyanide gun, which uses a similar trigger principle. The only animals caught by the Collarum™ have been canines. The trigger and spring-loaded action distinguish the Collarum™ from other devices which can be very indiscriminate in what they capture.
The Collarum™ is much more humane than existing traps. In a study conducted by the Predator Research division of the National Wildlife Research Center, Dept. of Agriculture, (Texas, Feb. 1999), 70% of coyotes caught showed no significant injuries, while the most prevalent damage was to the teeth in approximately 1 of every 5 animals. Most dogs and fox sustain substantially less damage because they fight less than coyotes. The recent development of the Relaxalock™ cable assures an even more “dog-friendly” capture.
This trap is much safer to utilize in areas where people, pets and other domestic animals may come in contact with it. An unknowing human springing the Collarum™ is at little risk. Animals other than canines are very unlikely to be caught by this device even if they spring it, and captured domestic dogs can be released with no harm done. Unlike cage traps which are large, bulky, and difficult to conceal, the Collarum™ is light, compact, and easy to hide. This gives it distinct advantages for Animal Control Officers (ACOs) in high visibility areas. The Collarum™ has also proven its effectiveness in capturing animals that won’t approach a cage trap or tolerate the close approach of humans.
