I'm a big fan of custom kitty goods, especially when they're totally adorable and can be worn right over your heart!
Jill of The Dapper Toad has created a new line of handmade cat charms that can be personalized, or used to symbolize your favorite kitty. For $42, she'll create a charm based on photographs of your cat, that can not only be worn as jewelry, but also displayed as a tiny work of art! If you have more than one kitty, and don't want the others to get jealous, she also has listings for 2 - 3 cat households, available at a slight quantity discount.
Don't have a cat, or are ok with having a piece that doesn't match your kitty down to the last whisker? She also sells pre-made designs of different breeds, such as the Siamese, Maine Coon, Norwegian Forest Cat, and American Short Hair.
