When dogs are faced with new stimuli, such as a new pet, a new boyfriend, or a trip to the vet, they usually respond positively, exploring new creatures and locations excitedly. Cats, on the other hand, tend to fly towards their favorite hidey-hole, often sneaking into the room occasionally to take short peaks at new pets or people. Overall, they prefer not to take car rides, and do not make friends with the local veterinarian. In nature, felines of all sizes prefer fleeing to fighting.
Fear aggression results from cats not being able to escape to a safe hiding place. When they feel that they can't get away, they sometimes turn combative. Situations such as previous abuse, not enough socialization, or sudden loud noises can bring on this behavior. Physical pain, such as arthritis or bad teeth, or medical conditions such as hyperthyroidism or physical injury can also add to fear-based hostility.
Symptoms of fear aggression are easy to spot. Cats will make their feelings abundantly clear. The felines will hiss, spit, growl, howl, crouch low or arch their backs, flatten their ears, and puff up like a porcupine. If physically confronted, they will lash out with claws and teeth.
Cats who continually react in this manner should be taken to the veterinarian so illnesses and injuries can be ruled out as the source of the behavior. If the cause is physical, treatment for the ailment should cause the cat to cease its hostile actions. If the cat is not sick or hurt, behavior modification is often recommended.
Take the doors off the pet carrier, and put in a soft blanket and some kitty treats to get your cat more comfortable with its carriage. Don't only pull it out when it's time to visit the vet. Make it a comfortable, non-threatening place.
Never use physical discipline with a scared and angry cat. That form of correction will only increase the feline's violent reaction. Clapping your hands once or twice to divert kitty's attention is a better solution. Make sure the cat has access to a place that makes it feel safe and comfortable.
Exposing a cat to frightening stimuli for short periods of time may help the cat become more comfortable. Non-aggressive behavior should be rewarded with treats. A new pet should always be introduced gradually. If a cat is frightened of other people, they should not reinforce the cat's aggression by walking away. Often by just staying in the cat's vicinity while ignoring it, the cat will learn that it's not under attack and calm down.
In more pronounced cases of fear aggression, medication prescribed by a veterinarian can be combined with efforts to desensitize kitties to the objects or situations that frighten them.
As any cat owner knows, there will be no peace until the little beasts are content.
