Abstract: A safety collar for cats having an adjustable neck-encircling band including a pressure releasable fastener. The fastener includes a socket type keeper member on one end of the band receiving a bolt member on the other end of the band. The keeper member has a restricted circular entrance including a radial slot opening into an internal cavity. The bolt member on one end has a ball larger than the circular entrance with a pin radially disposal in the ball and adapted to be received through the slot when the ball is forced through the entrance. The bolt at its other end is pivotably mounted in the band for aligning the pin with the slot for entry into the cavity and for release therefrom should the collar catch on some object, and for rotating the pin approximately normal to the slot for use as a conventional leash.
