Like wool sucking, earlobe sucking is a replacement behavior in many cases when the kitten was not weaned or weaned too early. Some cat owners don’t mind this behavior but it can become disruptive at times, an example being if an owner is awakened by their cat engaging in this behavior in the middle of the night. The best way to put a stop to this behavior is prevention. If your cat is performing this behavior she will be forced to stop if you stand up. For about five minutes pay no attention to her whatsoever, this includes not looking at her. If done with consistency, those cats who are not compulsive earlobe suckers can learn that their behavior will not give them the results they were looking for, either attention or comfort. Try to encourage your cat with chew toys, and if the behavior persists or becomes excessive, consult with your veterinarian.
