National Leash Thin Mountain Rope Dog ID Collar - Plum Punch -XS/Toy Size (6"-12") - The Original Snickers Collar

I love that these are practically invisible on my long haired white cats. I also love that they will slide fully open if they get snagged allowing the cat's head to slip out, but they stay on otherwise. I do not recommend the "breakaway" version of this color. My cats bite and open the clasp on those. The regular version like this is a very slim, very sturdy, very safe. The only collars that I have used for ten years.

I love these collars! I have had several. Only problem is I don't recommend them for long haired dogs. (But that is just my findings) My Bernadoodles hair is always getting stuck where the sliders are to adjust the size. Otherwise for dogs with shorter hair (hers is about 3 inches) they are perfect.
