Ah yes, brings back fond memories of when we called Tassy
"The Devil Child". Tassy bit from the second I saw her. I
picked her because when I put my arm in the cage full of
ferrets, she clamped on and bit me. Personality!!
It was *extremely* difficult to train her. She went after
toes, ankles, arms, she nailed my nose at least twice, has
bitten Phil's cheek, etc, etc, etc.
The biting of the arm is normal, we call it***-lick-chew-chew.
We let her do it once, positive it is a sign of affection, and
then scruff her, tell her "once is enough" and put her down.
She resisted socks, shoes, bitter apple, threats of being
turned into a muff, everything. There were times I would
have gladly offered her to the nearest cat. And she gets
all the others riled up, too, so they bite when they're
Sometimes it does take an extremely long time to nip train
them, and even then it doesn't always work. Have you tried
spraying her with water? Highly affective on mine, whether it
is digging at the carpet, climbing something or what not.
I don't really have too much advice other than keep plodding
along, you do see results. I still scramble for safety
every time Tassy starts climbing under the bed covers, and
I never stick my nose in her face for kisses like I do the
others, but she is still much better.
