Pets love the great outdoors, especially tall shady trees to sniff, dig around or climb. Cats will be cats, and when a bird is begging to be pounced on, or a tree branch looks like a spiffy perch for lazy gazing, it's only a matter of time before they're up the tree. And dogs know the best smelling stuff is always buried in the soil at the base of trees. So, it's no wonder this tag is so popular! Colorful and well crafted from ultra-durable steel core, our pet ID tags, featuring cat ID tags and custom dog tags, will never fade and are built to last.
