What is Respo-K?

Respo-K is the premium homeopathic cold medicine for your cat or dog. It is a safe and effective, non-addictive, natural remedy containing 100% homeopathic ingredients especially selected to temporarily relieve cold symptoms in your pets. Formulated by our team of experts in natural medicine, Respo-K effectively relieves the symptoms of respiratory irritation and acts as a decongestant for cats and dogs.

Respiratory difficulties and colds can easily be transferred from pet to pet whether you’re in a multi-pet household or a single-pet household. Everyday occurrences, such as taking your dog to the dog park or your cat to the groomers, can result in your pet catching a cold and beginning to show symptoms almost immediately. Additionally, if he or she is showing signs of respiratory irritation or nasal discharge, those germs can be transferred between pet just by sharing the same toys or food bowls.

Discharge from the nose and eyes, congestion, lethargy and lack of appetite are some of the first symptoms to look out for before administering Respo-K, to ensure the entire household stays healthy.

A powerful homeopathic formulation for the discomfort associated with respiratory upset, Respo-K uses a unique, proprietary blend of highly diluted natural substances to help reduce frequent sneezing and watery eyes, as well as fits of coughing in both cats and dogs. Sambucus nig has a long history of providing successful relief for pets experiencing obstruction in the nose, hoarseness and mucus in the larynx.

However, our team of herbalists, naturopaths, homeopaths and responsible pharmacists know that a couple of ingredients do not provide a full solution. Therefore, we have created a unique blend of five scientifically selected ingredients that enable Respo-K to provide a natural, effective and safe choice for optimal lung functioning and easy breathing.

Respo-K also includes Ferrum Phos, a highly effective ingredient for congestion of the lungs, as well as Hepar sulph calc, which is especially useful for dry, hoarse or rattling coughs.

For more than 200 years, homeopathy has been used to provide relief for a broad array of symptoms from a number of health conditions (acute). It uses the premise of like-treats-like to help with this symptom relief, demonstrating that these natural ingredients can provide gentle relief for the same symptoms that at full-strength they cause.

Unlike conventional medicine, homeopathic remedies have no known side effects, no interactions with prescription medicine or herbal remedies, and no contraindications with pre-existing conditions.

Respo-K is presented in two convenient forms, tablets or spray, and either form may be taken depending on your pet's preference. Both forms are easy to administer without fussing or fighting. The tablets can be crushed and sprinkled on the tongue, dissolved in water or given as whole tablets, while the spray can be administered directly into your pet’s mouth or sprayed on their food or water.

AmazaPet™, our homeopathic medicine for wheezing and chest discomfort, is a great complementary remedy to Respo-K.

Respiratory health through systemic support

There are many ways in which respiratory health can be encouraged in dogs and cats. A pet should be given a healthy, balanced diet all year round, and unhealthy treats should be avoided.

Regular exercise will help to promote respiratory health in your pet. However, pets of advanced age should be allowed to rest and be given ample opportunity for quality sleep. Don't overexert a pet – especially if they don't quite seem themselves.

The natural way

Natural cold remedies for cats and dogs can help to support the health of the respiratory system, including the nose, throat and lungs, and promote a healthy immune system. Dog and cat congestion remedies have also been used for generations to encourage respiratory health and support the lungs and sinuses.

Dietary recommendations for optimal health and immune functioning:

  • Many holistic vets will agree that the more raw food (as opposed to cooked meals or dried commercial pet food) the animal eats, the fewer general health problems there will be. Ideally, the best diet for a cat or dog is one which most closely resembles that which he would find in the wild.
  • For cats, who are largely carnivorous, this should consist of mainly raw meat (minced beef and chicken, chicken livers) mixed with a little bone meal and a small amount of some grated carrot or finely chopped greens like spinach.
  • Dogs will do well if more chopped and grated raw vegetables are added to their diets. We also recommend raw meat and raw bones for dogs, mixed with grated raw vegetables and chopped salads.
  • A teaspoon or two of olive oil added to the meal every day (depending on size) will also be beneficial. Do not give your animals any milk at all – nor products containing sugar.
  • Remember that you should not try to change your pet's diet overnight, especially if the animal is elderly. Slowly introduce new foods and allow the digestive system to become accustomed to the new diet.

    At first I was skeptical but after using Respo-K on my cat who has serious respiratory irritation. I'm a believer!! I've used for about 4 months and my cat is much better. The breathing attacks are very rare now. Thanks for such a great product!!
  • Clears up colds!

    Whenever any of my cats come down with chest congestion,
    coughing, or sneezing, I use a combination of Respo-K and Sinu-Rite. They get relief within hours and the infections seem to
    clear up in a matter of days. I feel so much better about using these products.

    This product did what it said it would do but my cats had more respiratory issues than just a cough. So I change to the Sinu-rite, Ammaze, They have both worked very well.

    I used your Respo-K remedy for my kitten when she got a cold. I was really worried about her as she is still so young and fragile. By the end of the weekend, she was looking much better and was eating again. By Wednesday she was her old self again. I have a friend whose kitten died from something as simple and “minor” as a cold so I am really relieved and grateful. Thank you!
  • Helpful for relief of congestion

    The Respon-K has helped his congestion.
  • Works for our cat with Chronic nasal discharge
    Posted 4/4/2013
    5 / 5
    We have been using Respo K and
    Sinu Rite for three years now with one of our cats who has chronic nasal discharge. She wouldn't be able to breathe without
    daily use. I tried several times to cut back and within a day she is in trouble. We also have used it on feral kittens. I
    highly recommend both products.
  • Purchased to have on hand
    Posted 3/2/2013
    5 / 5
    Fortunately we haven't had to use the Respo-K that I ordered yet. Am hoping we won't have the occassion, but having used other Native Remedies, it gives me good comfort having this one on hand. I gave 5 stars in advance because I rate the other Native Remedies we have used as 5 star.
  • Great Holistic Alternative
    Posted 2/24/2013
    4 / 5
    I have a two year old cat that has had congestion
    issues since we adopted her from a shelter at kittenhood. Our vet has noted that she has a form of upper respiratory that is
    not necessarily cure-able. My husband and I keep our cat on a daily regimen of L-Lysine mixed with soft food and three Respo-K
    tablets (morning, afternoon, before bed) hidden in bit of Greenies Pill Pockets. While this product has not taken her
    congestion away completely, it helps her to maintain a lower level of congestion (no more whistling nose), and allows her to
    breath better. Overall, I would definitely recommend this product.
  • Great for cats with allergies
    Posted 2/21/2013
    5 / 5
    I have a 4 year old tonkinese who has abominable
    allergies. For 6 days he had woken me up in the middle of the night struggling to blow clear his nose. I began giving him
    Respro-K 3 times a day starting the 4th night and ran a humidifier as well. It took about 3 days to fully help and last night
    was his first all clear. This is a great single-dose, natural product that I strongly recommend as an aid to pet parents who
    have allergy stricken fur-kids.
