Oliver is such a mean kitty that when I take him to the vet
(where they have him filed as "cranky"), the doctor jumps back
in horror when she sees him (and not in a joking manner). An
assistant has to come in and put him in a restraining device
(please keep in mind he was just 5 months at the time and quite
small) during his examination.
In addition to his behavior at the vet, he is quite a bully
at home. A friend compared Oliver's behavior towards me to an
abusive relationship. He bites my ankles, arms and nose and
slaps my glasses off my face and then, when its time to go to
sleep, he curls up around my head, purrs and tries to groom my
hair.
In order to calm him down, I got him a pet--his twin brother
from the same litter, named Beanie. Beanie is sweet and cuddly.
On two occasions Oliver saw Beanie sitting on the side of the
tub while I was taking a bath, shoved him in, and ran off.
