The odd one out is the odd one homed (6, really.. She's called Loreta now). All the plaid/tartan kitties in this photo are homeless. I call 2 & 3 Sherlock & Watson as they are made out of more suiting material. 1 & 4 are flannel. 5 is shirting material. 6 can be re-made upon request as I still have the material.
