Is your cat one to fly through the door every time it’s open? Make sure they always make it back home safely & quickly by getting them their very own personalized ID tag for their collar. Our space ring design is cute & minimalist all in one. Available in black, silver, gold, or rose gold. 2 different design options to choose from on the ring. The standard size will be the best fit for most cats. The large is intended for large-breed cats & other pets.
