DEAR DR. FOX: We have a pair of sister cats who we rescued four years ago. Up until the last month, they exhibited normal indoor cat behaviors, such as eating and sleeping together in peaceful harmony. One accidentally got outside for about two hours; upon being let back inside, she became cattus non grata to the other cat, who started hissing, spitting, etc. The one who had been indoors even bit the escapee on the tail and drew blood.

They are now being very hostile toward each other, with both going back and forth being the aggressor. We keep them in separate rooms in the house as any contact results in hissing, spitting and even growling and screeching. I have bought Feliway and put them in a room with it for a couple of hours at a time, but upon exit of the room, there does not seem to be any change in mood. This has been going on for a month, and I have been playing referee to a game of musical cats. I would appreciate any help or suggestions, as I want my happy home returned. -- E.T., Vienna, Virginia

DEAR E.T.: You are going through what my wife and I did after one of our cats got outdoors for a while and was attacked by our other cat, who was formerly his playmate and sleeping companion.

This "cognitive dissonance," or whatever is going on in the cat's psyche, is triggered by a change in pheromones in the cat who went outdoors, possibly set off by fear or by becoming hyper-alert and engaging in scent-marking and picking up the scents of other cats.

You will have to go through the steps of reintroduction. This includes rubbing both cats with the same moist cloth every day so they become accustomed to each other's odors and having them in separate rooms but able see each other through a screen door. Feeding them at the same time is also part of the resocialization process. The synthetic pheromone product you used is sometimes, but not always, effective.

STOPPING THE WORST TORMENT OF ANIMALS IS ENLIGHTENED SELF-INTEREST

As an evolving species, humans are living in the Anthropocene age, the apocalyptic consequences of which we are witness to today. These include climate change, ocean acidification, deforestation and loss of biodiversity with accelerating extinction of wild plant and animal species. Awakening to these anthropogenic (human-caused) concerns, which affect our health, security and quality of life, is giving birth to what my friend, the late Father Thomas Berry, called the Ecozoic era of ecological and environmental awareness and responsibility. This transcends the prior human-centered worldview with active planetary CPR -- urgently needed conservation, preservation and restoration.

The heart of this redeeming era, which some see as vital to our species' future well-being, if not also survival, is in bioethics. Bioethics essentially expands the empathic and egalitarian principle of the Golden Rule to embrace all sentient beings, plant and animal, wild and domestic. It is enlightened self-interest to do so, as the One Health movement, which connects animal and environmental health with human health and well-being, is advocating.

From a One Health perspective, no sane society can continue to justify violating this Golden Rule in its treatment of animals raised for human consumption in cruel factory farms across the Americas and most of the "civilized" world. These concentrated animal feeding operations (CAFOs) cause serious groundwater and air pollution and are a major contributor to climate change and loss of biodiversity. Wildlife and their habitats and precious fresh water are sacrificed to produce the feed for these poor farm-raised animals, who are fed increasingly from impoverished, plant nutrient-deficient and petrochemical-saturated soils and genetically engineered, insecticide-producing, herbicide-contaminated crops.

The animals are stressed by extreme confinement in overcrowded conditions that cause suffering and disease. Some of their diseases, many brought on by stress, affect consumers who are also put at risk by the antibiotics and other drugs used to prevent and treat animal diseases and boost productivity.

Millions of animals live under the constant torment of having no relief, escape or diversion from the stress of being overcrowded and deprived of being able to execute normal behaviors. Then they fall victim to live transportation to mass-slaughter processing plants. Their cries of pain and terror are natural signals of distress that have evolved because they are socially and emotionally conscious beings. To treat them without regard for this high degree of sentient awareness is the industrial norm. Farmed animals, like animals exploited in other contexts, are seen as property, objects of possession, mere commodities. Such objectification is the product of anthropocentrism and is its nemesis.

The net result of this abuse and waste of natural resources and inhumane exploitation of other sentient beings is dysbiosis, or ecological dysfunction, which includes the microbiome of our own digestive systems. The health of this internal bacterial garden that nourishes our bodies and protects us from disease depends in large measure on what we consume and feed to the animals under our care. This recognition is a first significant leap of science and medicine toward bioethically directed and inspired behavior. The links between the One Health movement, humane and organic farmers and informed and concerned consumers give me some hope.

Opposition to the enactment and enforcement of farmed animal welfare and environmental protection laws calls for public boycott in the marketplace, where concerned consumers vote with their dollars.

DEAR DR. FOX: I have a 3 1/2-year-old Akita mix who has been with us for the last two years. At first he was very aggressive with other dogs. It's getting better, but he has a way to go. Any suggestions?

Also, he has a strange habit: My daughter has a pair of plush leopard-print slippers that drive him crazy. He will drag my daughter around trying to remove them and starts to bite until we take them away. What do you think? -- B.H., Bethesda, Maryland

DEAR B.H.: I would get your daughter a plain pair of slippers and let your dog have the old pair for himself to fetch and "kill" while you engage in interactive play with him; otherwise, he may not respect physical boundaries. He could play too roughly and injure your daughter.

This breed can be assertive toward other dogs, which can become a problem when they are in their young adult stage (1 1/2-2 years old), and neutering is no guarantee of subduing dominance aggression. So your dog needs to be educated to develop self-control and internal inhibition, beginning with basic sit and stay training.

Spending time with a dog he likes in an off-leash enclosed park would be a big step toward dog-dog socialization.

DEAR DR. FOX: When my daughter moved into her ground-floor apartment, she discovered her cat, Reese. According to the custodian, Reese had been abandoned by her owners and for about three years had been living with a cat colony that took shelter in a nearby sewer. My daughter was able to gain her trust and take care of her with plenty of patience. They are both living with us for a while, and Reese has warmed up to all of us, even Lucy, our labradoodle.

However, Reese's rhinitis was out of control. Our vet assured us that she was contagious only to other felines. After a round of antibiotics, our vet suggested we try lysine drops in her food, as the condition is most likely herpes based. It has worked beautifully. She still sneezes and wakes up with drainage from her nose, but her breathing has improved and the condition lessened. My daughter also uses a steam humidifier on the occasion of a more intense flare-up.

Reese is a contented indoor cat who is still wary of strangers and refuses to be picked up. However, she cuddles with my daughter and looks to be petted by the rest of the family. -- J.M., Brick, New Jersey

DEAR J.M.: Thanks for confirming the evident benefits of giving lysine supplements to cats with compromised immune systems due to chronic herpes virus. A few drops of fish oil in the food can also help because of the oil's anti-inflammatory properties. And never discount the benefit of a biologically appropriate diet.

Chronic nasal discharge in cats is a common malady, and in some cases, the underlying issue is gingivitis, stomatitis or other dental problems, which can lead to sinus infection, tooth root and surrounding bone infection and erosion.

PET FOOD INGREDIENT MISLABELING INVESTIGATION

Pet food testing in Europe has found that 14 of 17 pet foods included meats not identified on product labels. Lack of pet food transparency is a worldwide concern.

Susan Thixton at truthaboutpetfood.com reports:

"In this study, researchers tested 17 popular brands of pet food sold in Europe. The study looked for animal protein sourced from cow, horse, pig and chicken. Of significant concern, 'there was detection at substantial levels of unspecified animal species in most products tested.'

"Unspecified animal species could be any animal other than cow, horse, pig and chicken."

Let us hope these researchers will do further DNA analysis to determine the exact animal that was dubbed "unspecified."

This problem has been noted in pet foods in the United States, too, and it is a grave issue in feeding dogs who are allergic to or intolerant of certain animal proteins, such as beef or chicken. It is also an ethical issue for purchasers who may wish to avoid feeding their dogs pig or horse meat. The questions of where the pet foods were manufactured and country of origin of ingredients include ethical and health concerns that have yet to be answered.

DEAR READERS: Since the publication of the book "Sugar Blues" by William Duffy in 1975, there has been rising consumer awareness over the healthfulness of sugars in the human diet. Much research has been conducted, yet ever more sugar is consumed worldwide as food manufacturers deny the risks. It is not mere coincidence that a cluster of serious diet-related diseases in humans are also seen in cats and dogs, and these can be prevented and often reversed with sugar-free, biologically appropriate diets.

Many diseases that affect us and other animals, wild and tame, are anthropogenic -- brought on by ourselves -- through our collective misuse of chemicals, drugs, natural resources and ecosystems. Some of these causes of the "diseases of civilization" will not be rectified for generations, if ever. But others can be addressed, notably what we choose to eat and what we feed our companion animals, beginning with cereal-derived carbohydrates and sugars.

Dogs are more carnivorous than omnivorous humans, while cats are absolute ("obligate") carnivores. All of these species, cats in particular, are harmed by refined sugars and those derived from high glycemic index carbohydrates, which the bodies of cats, dogs and humans convert into sugars, triggering insulin release and storage of the calories from sugars as fat. Cereal glutens, phytases, genetically modified organisms, herbicide residues and various chemical and pharmaceutical "obesogens" (foreign chemical compounds that disrupt normal development) may be co-factors in diet-related health problems.

The health issues our cats and dogs now suffer from are telling us that what most of us are eating and feeding to them is wrong -- biologically inappropriate diets high in sugars for humans and high in starches for all three species. These health issues include: dental problems; oral and intestinal dysbiosis (disruption of health-promoting populations of bacteria leading to hyper-reactive immune systems triggering allergies and autoimmune diseases); fatty liver disease; obesity; metabolic syndrome and inflammatory diseases arising therefrom, including arthritis and some cancers, heart disease, high blood pressure, eye disease, diabetes, pancreatitis, chronic pancreatic enzyme insufficiency, inflammatory bowel conditions, kidney disease and urological problems, especially in cats.

For humans, I recommend eating less sugar and only a modicum of functional complex carbohydrates in their diets (i.e. cruciferous vegetables; fresh, whole fruits -- but not grapes; gluten-free grains; green, leafy vegetables; and legumes rich in phytonutrients and prebiotics). For most dogs, add only some complex carbohydrates to their diets; for all cats, a minimal amount (approximately 5 percent of the diet) of carbohydrates is called for. For more details, see "Not Fit for a Dog: The Truth About Manufactured Cat & Dog Food" and "Smart and Canine Nutrigenomics."

DEAR DR. FOX: I have a 12-year-old cat named Gabby. I have been taking her to the vet for regular checkups, and he says she is in perfect health for her age and is very active and alert. She loves to play, and she sleeps well. But sometimes she has this deep cough that almost sounds like kennel cough, and sometimes it's almost like she is having a hard time swallowing.

This only happens once in a blue moon. Most of the time she is in great health. I've told the vet about this, and he says it might be an allergy or something like this.

We also have a dog named Max. He is a beagle, and he is 13 years old. He has a partially collapsed trachea and is prone to bronchitis and pneumonia, and he has chronic cough.

What suggestions do you have for my dog and cat? Thank you for your time. -- J.B., Fargo, North Dakota

DEAR J.B.: These two issues are not uncommon in canine and feline companions.

The first possibility to consider for your cat is that the sound may be from gagging up hair balls. Cats do not always vomit these; instead, the gagged-up fur is swallowed and eventually evacuated. In some instances, it can accumulate as a mass in the stomach and must be surgically removed. Adding a little olive oil to the cat's food and giving her some high-fiber treats can help, as can daily grooming.

Dogs pulling too hard on the leash and wearing collars can damage their tracheas, as do those idiot people who discipline their dogs by jerking and snapping sharply on the leash. A Gentle Leader or harness is safer and less injurious for dogs who pull hard on the leash.
