Redirected Aggression in Cats

Cats display a complex behavior known as redirected aggression. According to Dr. Debra Horwitz, ” Redirected aggression arises from the cat being in an aggressive or agitating circumstance, but unable to vent that aggression on the causative agent.” Here’s a common history. A cat is looking out the window and sees another cat invade their yard. The angry cat wants to attack the intruder lurking on the other side of the glass. Since they can’t, they attack whatever is close. This can be humans or other animals in their immediate vicinity who are innocent bystanders. The victim is in the wrong place at the wrong time. Redirected aggression can be caused by the sight, sound or smell of another cat or animal. Less frequently, unusual sounds, unfamiliar people or objects and even pain may trigger an episode.

Treatment is based on removing the inciting factor from the cat’s environment. This is often easier said than done. For outdoor cats or other animals, cover windows and remove perches and furniture from the area. Remove any sources of food, water and resting places from the yard that may attract other cats or animals. Discourage visiting cats with motion detector air canisters or water systems that provide a surprise shower. Shield the cat who suffers from redirected aggression from windows by blocking their access to the window. Removing furniture and/or covering the window will work for cats who are visually aroused but may not be enough if scent is the trigger.

Once a cat becomes aroused, it should be left alone to calm down. Create a safe room for the cat that contains a litter box, water, food and a Feliway diffuser. Gently herd the cat to the room with a broom or box. A cat in this state of arousal may inflict serious damage on people or other animals. Take extreme caution to avoid injury. If the cat must be picked up, use a thick quilt wrapped around their entire body including the head. Once in the room, turn the lights off and leave immediately. Give the cat plenty of time to calm down before entering. For some cats, it may be several days before they are back to normal. A video camera placed in the room is a great way to access their state of arousal from a safe distance. An aroused cat will have a bushy tail, dilated pupils, flattened ears and growl as they pace about the room.

If the inciting cause cannot be completely removed from the cat’s life, then counter-conditioning and desensitization may help control re-directed aggression. The cat is exposed to the stimulus at a low level and then rewarded for good behavior. Slowly the cat will learn to associate the stimulus with good things as the feelings of anxiety disipate.

Blue Buffalo and Wellness Voluntarily Recall Dog Food After Three Dogs Suffered From Thyroid Toxicity

On March 17, 2017, the FDA announced that Blue Buffalo and Wellness dog food companies were voluntarily recalling some of their products because of excessive levels of beef thyroid hormone. The food contained gullets which are the larynx from cows and steers. Unfortunately, the gullets were not properly cleaned and contained thyroid glands which was the source of the toxicity. Three dogs from different households including a Shetland sheepdog, Tibetan terrier and Labrador retriever became ill. Thankfully, all of the dogs recovered once the food was taken out of their diets.

Clinical signs of thyroid toxicity, also called hyperthyroidism, include increased appetite, thirst and urination. A common clue is that weight loss despite an increased appetite. Another common clue is restlessness or an increase in activity in a senior pet. Some people describe it as, ‘acting like a puppy again.’ If left untreated, chronically elevated thyroid levels may cause vomiting, diarrhea, heart disease and death.

Diagnosis of thyroid toxicity is based on physical examination and laboratory testing. Animals with hyperthyroidism have elevated total thyroid hormone levels in their blood. They may also have other blood and urine abnormalities due to the far reaching effect of this hormone.

If you feed BLUE WILDERNESS or WELLNESS, please check for the following products that have been voluntarily recalled, stop using them and contact the company immediately. Here’s the list:
