My dog and cat key fobs make great gifts for animal lovers. Use them as key rings, luggage tags, or to decorate your purse, bag, backpack, lanyard, etc. You can unsnap it to remove the key ring. 
 
This design works great both for Boston Terriers or French Bulldugs - and mixes of the two.
 
The Cat Butt Key Fob comes in three colors: white, black, and brown.
 
Most key fobs are approximately 3.75 x 3.75 excluding key ring. Individual designs may vary in size slightly.
