Cats are so good at expressing themselves, aren't they? How sweet that she gets jealous if your attentions aren't on her! Scooter gets a little jealous if his daddy is paying attention to Marius, because he only wants attention from his daddy...and Marius could go either way. LOL Although, it is evident that we really do have his and hers cats! Scooter is such a daddy's boy! LOL
Be sure to tell Edwina that she hasn't been replaced and that she's still your favorite cat! LOL
