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.
