our cat spent the first 6 years of his life in a home with dogs...then this past summer i had to put my beloved chocolate lab down (she was 14). hubby and I decided when our present pets are gone...that's it, we are not getting more...so, the Kimba cat found himself suddenly an 'only child'...he has taken up some pretty funny habits in the past few months...he scratches/shakes his collar just right so it 'rattles'just like the dog's used to. Used to be if anyone came to the door he would run and hide under our bed or in the closet...now, someone comes to the door, he runs to it...just like the dog used to....the dog used to (for 14 years) lay right under my sewing table when i'm sewing...yup...now the cat spends his time there...he's a very funny cat. it's like he feels he has to play both parts now, he flopps down and sighs, just like the dog, ...cats are funny critters ! :)
