The Honey Zee.Cat collar is made of super soft polyester and is one size fits all. This fully adjustable collar has a breakaway buckle that automatically opens if your cat gets stuck.
My skittish cat finally got himself wedged behind a bookshelf the other day, and the collar unclipped just like it should instead of choking him. The polyester is genuinely soft too, so I don't feel bad leaving it on him all day, and the adjustability means it fits even his skinny neck.
The breakaway buckle gives me real peace of mind since my kitten loves squeezing under the couch, and the soft polyester doesn't irritate her neck at all. It took less than a minute to adjust to her size and it's held up perfectly through her daily zoomies.
My cat got his collar snagged on a branch last week, and the breakaway buckle did exactly what it should—popped right open and he walked away completely unharmed.
