DEAR READERS: The Natural Resources Defense Council (NRDC) is filing suit against the Environmental Protection Agency over its continued approval of flea collars and powders. These products can put children, in particular, at risk from their highly toxic chemicals, as well as other animals in the home.

For details on the suit, visit nrdc.org/fleaproducts. The NRDC is also challenging the EPA over its continued approval of the herbicide Roundup, whose main ingredient, glyphosate, is linked to non-Hodgkin’s lymphoma.

When governments fail to protect citizens, other animals and the environment, personal responsibility is called for in the name of Earth justice and respect for all life.

DEAR DR. FOX: In your article about the benefits of children being in contact with livestock, you mention animals at petting zoos in state fairs.

I would like to point out that, at a lot of those fairs, there are livestock animals in exhibits that are privately owned. I would like to remind readers that these animals are not part of the petting zoo, and should not be touched without permission from the owner. They are there as show animals and may not be accustomed to strange people touching them.

I speak from experience. I have a horse that I take to the local fair, and I usually have to hang a sign on her stall telling people not to touch her. We take our animals there because it’s fun for us, and we want to share their beauty with everyone else. The majority of people passing by respect the sign, but there are some who don’t. My horse, when spooked, will slam herself against the stall door. If someone has their arm in between the bars to pet her, they could end up with a broken arm.

When visiting fairs, please obey the “Don’t Pet” signs, and always ask permission to pet an animal. -- S.A., Saylorsburg, Pennsylvania

DEAR S.A.: I would never leave any animal in an enclosed space without a person present when at a state fair, or any other outdoor event with large crowds, unpredictable adults, rowdy teens and curious children with inattentive parents. I adhere to the general rule of protecting animals wherever there are people, rather than the reverse!

I firmly believe that some animal exhibits should be prohibited for humane and public health reasons. Sows, for instance, would normally build a nest in a quiet spot before giving birth, but at state fairs, they are in pens surrounded by a gawking -- and sometimes screaming -- public. And that is after enduring transportation over long distances in late pregnancy.

Just this summer, public health authorities traced a strain of E. coli 0157, which can sometimes be fatal to humans, to exposure to pigs at the Minnesota State Fair’s Miracle of Birth exhibit. (Minnesota Star Tribune, 9/18) Handwashing and footwear-cleaning stations will not suffice. Time to stop this exhibitionism of what, in my opinion, is unacceptable animal mistreatment.

DEAR DR. FOX: I have a 7-year-old Westie. When she was around 5, we discovered that eating turkey or chicken (whether freshly cooked or in packaged dog food) would make her sick. She would throw up, not eat or drink for several days and be very listless. Finally understanding the cause, I researched dog food labels and settled on a poultry-free, beef-based food from Whole Earth.

All was well for a couple of years, but then the same condition reared its ugly head. When nothing showed up from tests at the vet, I tried changing her food on a suspicion that the latest bag may have been contaminated with poultry. Almost immediately, she was better. Afraid it might happen again, I searched for a new food and settled on Zignature.

Once again, all was well, until I read one of your articles about dog food. I was shocked to see Zignature was second-highest on the list of cases tying it to dilated cardiomyopathy (DCM).

Will you please recommend some good dog foods that do not have poultry? We are running out of options.

Also, she has trouble from time to time with impacted anal glands. A friend has suggested giving her canned pumpkin for this issue. What is your opinion? -- T.W., Tulsa, Oklahoma

DEAR T.W.: Sorry to hear about your little dog’s issues.

Food allergies and intolerances can cross over from one kind of meat to another, so many holistic vets suggest a “rotation” diet, changing the kind of animal protein in the food every five to seven days. This can mean rotating among fish, eggs, cottage cheese, lamb, mutton, duck, high-protein pulses (lentils, chickpeas or butter beans, containing 250 mg taurine per serving). Your dog may need digestive enzymes, such as a tablespoon of papaya or crushed pineapple at each meal.

Try my home-prepared recipe, since many manufactured pet foods can contain animal proteins other than the main one or two indicated on the label, which is problematic for many dogs -- and for veterinarians trying to determine which ingredients may be causing problems.

Anal gland problems can be a sign of food intolerance/allergy, as can lack of exercise and too little fiber in the diet. Two tablespoons of canned pumpkin, oatmeal porridge or crushed white beans once daily can help.

DEAR READERS: While much of the public discussions about the climate crisis have focused on the future of humanity, there is rarely a mention of the plight of animals, and the biodiversity intertwined with our own well-being.

The Animal Legal Defense Fund is mounting a lawsuit designed to compel federal action against climate change: Animal Legal Defense Fund v. United States of America.

In New Jersey, the average temperature has already risen 2 degrees Celsius -- viewed as a critical threshold of climate change. As a result, blue-green algal blooms, potentially deadly to people and animals (particularly dogs), are plaguing the state. Similar blooms are happening in lakes throughout the country, and are linked to warming temperatures. Florida’s red tides have killed hundreds of manatees. On the West Coast, an exponentially high number of dead marine animals have been washing ashore, including gray whales and sea lions. Many are also dying from starvation.

For decades, the federal government has aided and incentivized greenhouse gas-producing industries like animal agriculture, logging and fossil fuel extraction. In addition to direct subsidies, the federal and state governments have exempted these industries from environmental protection laws regulating greenhouse gas emissions, water use and air quality.

This lawsuit, rooted in our Constitutional right to liberty, “would confirm that preserving wilderness should be the baseline for environmental protection,” said ALDF Executive Director Stephen Wells.

DEAR DR. FOX: I rescued my kitten from the freeway two years ago. According to my vet, she was only 4 weeks old at the time. She is the strangest cat I have ever had.

She eats everything in sight, except for food -- no people food, and not much canned cat food. She has eaten holes in my underwear, nightgown, socks, sweatshirts, bedspread, toilet paper, regular paper and cardboard. She has never seemed to have problems defecating, although it is dry. I have bought some feline vitamins; the directions say to give two, but I only give her one, and she gobbles it right up.

She follows me everywhere, so I know she loves me, but she is not an affectionate cat. When I try to pick her up, she growls and hisses. If I am lucky, I can pet her for about two minutes.

Most people would give up on her, but I care about her very much. Can you help me figure this out? My vet has never heard of a cat eating “things.” -- J.J., Central Point, Oregon

DEAR J.J.: Good for you for rescuing this little soul.

Her early food/nutrition deprivation could have triggered this compulsion to chew and swallow various materials, a condition called pica. She finds comfort in this activity, along with feeling full; the drive to experience satiety can have an addictive element.

It is important to keep all materials that could lead to intestinal blockage well out of her reach, as well as potentially toxic plastics. An abdominal radiograph or sonogram may reveal material accumulated in her stomach, which could call for surgical removal since it could disrupt normal food intake and digestion. Cats with large accumulations of fur balls in the stomach (often a result of excessive grooming) may also engage in pica and be malnourished as a consequence. Chronic gastric and intestinal irritation can lead to pica, possibly in an attempt to relieve the abdominal discomfort.

I would transition her onto my home-prepared cat food (see recipe at drfoxonehealth.com) and feed her 6-8 heaped teaspoons daily. If she refuses this food (cats can be finicky), give her a good-quality canned cat food, along with freeze-dried cat foods from The Honest Kitchen and Stella and Chewy’s. Most cats do best on several small meals daily; think of mouse-sized portions. Weigh her initially, and then every three to four weeks. Over time, you can increase or decrease the amount of each serving to maintain her optimal weight.

DEAR READERS: As a member of the American Holistic Veterinary Medical Association, I have been a longtime advocate of integrative medicine and a holistic approach to animal health, including the use of nutraceuticals and various botanicals. But I am concerned about reports that access to websites on these subjects as they relate to human health is now being blocked by Google, which has just contracted with the Mayo Clinic to “improve diagnoses, treatment and outcomes by mining the medical records of people ...” (Star Tribune, Editorials, Sept. 16).

Several years ago, when I gave a lecture at the University of Minnesota in Rochester -- the hometown of the Mayo Clinic -- I was told by the graduate student organizer that the university bookstore and the main bookstore downtown had both been instructed by “the powers that be” not to stock my controversial books on industrial agriculture and related environmental and consumer health concerns. Now, it would seem, there is further censorship that is proceeding at an unprecedented pace to further vested interests in conventional medicine, rather than advance the first medicine of prevention, and also the use of alternative treatments to various pharmaceutical products that are often costly and have harmful side effects.

For details, see naturalnews.com and healthnutnews.com. The latter reports that popular websites like Mercola and GreenMedInfo have lost significant visibility over the year studied (Mercola -84.02%, GreenMedInfo -81.14%), while the Mayo Clinic showed a 59.98% increase in visibility.

DEAR DR. FOX: My 3 1/2-year-old spayed female Boston terrier constantly licks and scratches. She has been on Apoquel for the last three years, which does not help.

Is there anything that can help her? I have tried different brands of dog food, but there’s been no improvement. Would holistic treatment help?

I also think she has psychological issues, and that may be part of her problem. It also seems that she does not sleep a lot, even during the night, as she is constantly moving and licking. -- B.K., Barnegat, New Jersey

DEAR B.K.: I would taper off the Apoquel, which is being widely prescribed for dogs, often with no benefit and sometimes with harmful consequences of suppressing the immune system.

Considering the breed, your dog could need surgery for an upper-respiratory obstruction related to having a pushed-in face, which can interfere with sleep and limit physical activity. Such dogs often need their nasal orifices enlarged. Difficulty breathing can cause restlessness and anxiety, can lead to secondary infections such as pneumonia, and also puts extra work on the heart. With reduced physical activity, obesity is another complication.

I am sending you my home-prepared dog food recipe, which will help rule out any possible food allergy. In addition, I would give her 1,000 IUs of vitamin D3 with each meal (three small meals a day). This supplement helps in some cases of atopic dermatitis in dogs for whom Apoquel has been prescribed.

Remember to weigh your dog before starting on a new diet, and then weigh her every three to four weeks to help maintain optimal weight.

BACKYARD CHICKENS? PLEASE THINK TWICE

Keeping your own chickens may be popular these days, but it is far from harmless. More than 1,000 cases of salmonellosis from backyard poultry had been reported in 49 states this year as of Aug. 23, resulting in two deaths and 175 hospitalizations, according to the Centers for Disease Control and Prevention. A CDC survey of patients found 49% of those infected had snuggled chicks, 46% allowed the birds in their house and 10% allowed them in their bedroom. (CNN, Sept. 14)

My advice is to resist being drawn into this trendy hobby, and keep children away from such backyard operations. If you do eat eggs, do your best to find those from free-range, uncaged hens fed organically certified food. If you saw how commercial layers are housed, you would never eat another egg.
