Hey birdgirl in the future what i bought for my cats out of fear of the same hanging and other horror stories is a Velcro collar because it is still great in identifying them but will not harm them they sell them at petcos and are great for protection from being lost or claimed as abandoned and still protecting them from a horrible demise for such great animals. I am so glad to here he is home didn't want to respond to this post in this way while he was missing you know what i mean.
I must add that all free rome pets should have Velcro collars not snap ot hole and post ones because what is your pets life compared to a collar and tag. Even my dog wheres a Velcro collar when at home and only during walks wheres a hole and post collar never a choker if you dog needs a choker he really needs to be trained and loved not abused through an abusive collar.
