KVP/KONG bird E-collars are made of tough, pliable, lightweight Lexan with “tight-snap” fasteners. The neck opening, which comes in eight snap-adjustable sizes, is padded with soft vinyl foam.
• Specially designed for birds
• Helps overcome feather picking and the itch-bite-scratch cycle
• Combines long-lived toughness, softness and light weight
Sizes reflect the bird's neck circumference, not the circumference of the collar. Please measure the bird's neck for proper fit. (For instance, the 1.4"-2" collar has a total diameter of 4". The 4.7"-5.5" collar has diameter of 10".
