These Haight Ashberry collars are made out of remnant yarn from the fabric industry. This gives each batch a slightly unique look while remaining in the color themes, plus it supports recycling! The reflective threads are highly reflective, which means they keep your cat visible & safe while they're out at night! Goli cat collars feature quick release, break-away safety buckles in case your cat gets their collar snagged while indoors or out. Collars are adjustable from 7.25" to 11.75" to suit different sizes of cats.
