Abstract: A predator control collar (10) includes a pair of toxic filled pouches (12) and (14) attached to elastic straps (16) and (18) for expansion. The pouches (12) and (14) include a fill plug (22) for a needle to inject a liquid predicide into the pouches. The pouches (12) and (14) are positioned about the elastic straps (16) and (18) so that they are maintained in the general region below the ear of the livestock, and the straps (16) and (18) are of sufficient elasticity to expand with the increase in the size of the animal's neck as it grows to full maturity.

Abstract: Apparatus by which a steel leg-hold trap is rendered humane so that the trapped animal is recovered alive and uninjured. A resilient material, such as vulcanized rubber, is removably affixed to the opposed jaws of the trap so that the animal's leg is uninjured when the jaws are closed thereon. The first reaction of any animal caught in the leg-hold trap is to bite and chew on the trap. A nipple extends from the resilient material and contains a substance, such as a tranquilizer, which subdues the animal when the substance is orally ingested. The nipple is a hollow chamber which extends away from the trap jaws so that the animal, when trapped, inherently attacks and bites the nipple, whereupon the chemical substance is released from the chamber and enters the oral cavity of the animal, causing the animal to become subdued. A tranquilizer is preferably placed within the nipple so that should the incorrect animal be trapped, he can subsequently be released unharmed.
