I'm a bit clueless. My two kittens are due to be neutered soon and after that I'd like to start letting them outside. They are chipped but I imagine a collar would be helpful if they wandered as I know some people could assume no collar= no owner.
Why type is best? Is there a particular material/ clasp that is better?
Also, I think I read here to just put a number on the collar and no name. Is this right?
