I'm probably one of the rare few that doesn't use break away or elastic cat collars except when I'm training my cats to them. All but my youngest 3 (I'm still working with them) are leash trained so I use small dog collars. I can't have a collar that allows escaping when I'm walking on a leash, one pull the right direction and they'd be free which would defeat the purpose of leashing them. Mine only wear their collars when walking on the leash, or traveling, the rest of the time they go naked. lol
