Although aggressive cat behavior can be unpleasant and downright
scary
... it is usually (but not always) - normal behavior.
Feline aggression is a behavior designed by nature to ensure
survival … a mad looking cat is usually only acting instinctively.
The good news is ...
Aggressive cat behavior - biting and scratching - can often be
predictable and controllable, a simple matter
of cause and effect.
Like us, cats have different personalities and temperaments.
Sometimes temperament is a matter of heredity or how early and
well your cat was socialized as a kitten.
Perhaps a disturbing or abusive experience, completely unknown
to you, comes into play.
Begin by understanding the reasons why cats bite and scratch
... Does your cat have an injury? Is it sick?
... How is your cat perceiving his environment?
... Is he or she feeling threatened?
... Or did a child just give him the mother of all bear hugs?
Secondly,
know and recognize cat body language
and vocalizations (cat sounds)
Cats do communicate with us ... but in their
own language ...
Before your cat slips into an aggressive mood and delivers
a scratch or bite he or she will usually provide you with plenty
of clues.
By being observant and acting quickly, you can often control
the situation and prevent your cat from biting or scratching.
Some signs are obvious and others easy to miss.
What you will see:
... its tail is
twitching ... and if very aroused ... lashing from side to side
... ears are turned
back or flattened (to protect them should it have to fight)
... its fur puffs
up (to make him look bigger)
... the cat is staring
... if threatened the pupils
of its eyes are enlarged (it can see better)
... he or she crouches
close to the ground, ready to spring
... it bares its teeth
What you will hear:
... unusual, angry meows
... hissing, growling and snarling
If you pick up on these warnings, then it is probably is a good
time to remove yourself ... and the trigger (reason), if you can
identify it, from the immediate area,
... or simply step aside ...
(big step) and allow it to 'escape.' Give it lots of space and
let your cat calm down. Wait until he or she comes to you.

Some reasons why
cats bite
Is your cat sick or hurt?
Any sudden changes in habits or behavior are often an indication
that your cat has an illness, injury or some
other source of discomfort.
Cats instinctively hide any signs
of pain or illness.
Fear ... does the cat feel threatened?
Angry looking cats are often just scared cats.
When afraid, they can act as we do - fight or flight.
Cats, if given the chance, would rather leave the scene than
stay and fight.
Create space between you and your cat. Make it
easy for your cat to leave. Move away and clear a big
path so your cat can 'escape.'
Redirected aggression
Simply put, your cat cannot direct his aggression (defensive,
territorial or other) to the target or trigger. So, instead
he lashes out at innocent bystanders - people or other animals.
(Sometimes people do it too.)
Is he frustrated because he saw another cat outside on his
lawn and he is on the other side of the window? Maybe he witnessed
or heard - what he considers to be - threatening gestures or
sounds.
Repeated aggressive cat behavior
Cats can make secret and mysterious associations with a triggering
event such as the ring of your phone, a certain scent, a resemblance
to a person or thing ... which could catapult your cat back to
another scary space and time and the aggressive behavior, such
as a cat attack, will suddenly be repeated.
Defending their territory from other
animals
By nature, even domestic cats are territorial - whether their
territory be a favorite chair or a large outdoor area.
In the wild, survival depends on the ability to defend hunting
grounds, to feed and protect their young.
Plain old jealousy
I have multiple cats and even though they all get attention,
my huge Maine Coon picked on my gentle Sunnyman. I had to be very
sure they were separated, when I was out and at night.
If you need more help ...
Uncontrolled, severe aggressive cat behavior or attacks can
be a serious threat to humans and other pets.
Do take your cat to the vet to eliminate any medical
causes for the aggressive behavior. Your vet may prescribe
mood stabilizers and/or refer you to an animal behaviorist.
Both can be very helpful.
Remember:
... know the warning signs (that
includes family and guests)
... don't hit or punish your cat. Cats do not understand
the concept of
punishment. They only know that
you are treating them badly and they
don't know why. The end result will
be a fearful animal, who will display
further aggressive behavior, and
justifiably so. It's a lose - lose situation,
and most importantly,
... love your cat and it will love you back.
