This is thought to be rooted into early kittenhood and many times other behavior such as drooling, kneading, and purring accompany this pattern. Another predicament is when they actually eat odd objects, this is called pica. Many an animal is rushed to the emergency veterinary clinic for extraction of these strange items. Sometimes the extraction results turn up nylons, underwear, toys and other such strange stuff. Nothing is safe when this type of cat is out and about.
Abnormal behavior can stem from a variety of areas.
If you have an animal that exhibits abnormal eating behavior, you should seek help right away. You need to get the help from the right sources. The three animal professionals you might want to see are the veterinarian, the animal nutritionist, and the animal behaviorist. Most behavior consultants will have you schedule an appointment to see your veterinarian before they will see you. This appointment is important since the purpose is to rule out any veterinary medical complications that may be the underlying problem showing up in abnormal behavior.
