I love the moth balls joke!
After reading everyone's posts, I have to agree that my cats both fall quite comfortably into the D/s roles.
TJ is my big cat - he's about 8 pounds, and so much better than everyone that it's kind of funny. Cali (creatively nicknamed for Calico) is small and frail, and incredibly skittish. TJ is always first to the bowl, demands supper at 9:25pm, and wouldn't THINK of touching a treat that Cali had sniffed out first! Cali on the other hand is perfectly content to sit back and let him have his way, chase her aroumd, and gnaw on the back of her neck when she's pissing him off.
Now if only my hubby would do the same for me!
