Revolutionary collar for cats kills immature fleas, adult fleas, and flea eggs for up to 8 months. Kills ticks for up to 6 months. For cats of any size over 12 weeks of age.
This collar is designed to stretch under the weight of an average sized adult cat. It helps the cat to free itself ("breakaway") if the collar gets snagged on a fixed object. If the collar is fitted improperly, so that it is loose enough for a cat to work the collar over its leg or jaw, this release feature may not stretch adequately to allow the extra room necessary for the cat to free itself.
