Respo-K is a safe, non-addictive 100% natural homeopathic remedy registered with the FDA and formulated especially for pets to improve respiratory health and strengthen immunity to help prevent the recurrence of secondary infections of the sinuses or lungs. Presented in two convenient forms, tablets (125 tablets per bottle) or spray, and either form may be taken depending on your cat'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 kitty's mouth or sprayed onto food or water.

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 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.

“A strong natural flea spray was put on my cats & not rinsed off....  The spray irritated my cats' throat and chest to the degree that they would not eat or drink water.  I ordered your Respo-K  .... The second day both cats ate some soft food and drank some water. I'm very pleased with the Respo-K. They have stopped coughing and that awful gurgling sound coming from their throats is also gone. They're back to playing and enjoying life! Thanks for making such a wonderful product.”
—Lucille S.

“Although I have been happy with everything I’ve ordered from you I must specifically comment on your Respo-K and Sinu-Rite products. I have one cat that often needs respiratory support. Last time I gave her Respo-K and Sinu-Rite and she bounced right back. I continued to give her the remedies for a little while after she was well again and she has been great. She actually seems much stronger and healthier overall. I am going to make sure I always have stock of these remedies in my house from now on!”
—Moira H.

“We have many cats and one is about 18 with…respiratory [issues] and congestion. She has been …[on medication] for many months. This seemed to help a little for a little while, but was steadily destroying her immune system. I didn't know what else to do until I found your website and Respo-K. It sounded possible for it to help, so I ordered some. Within 2 days I saw a significant improvement in her breathing and appetite. I have had her on it for 3 weeks, twice a day and she is eating well, her coat is fuller and she is putting on a little weight again. I was just about given up, but am so very thankful that the quality of her life has improved. Thank you!”
—Anne A., AR, USA

"My Persian had a hard time breathing and eating at the same time and was becoming very thin. After a week of Respo-K she was breathing great...She's putting on weight and really enjoying life."
—Bonnie, MI, USA

Respo-K contains the following homeopathic ingredients: Calc. sulph. (D6), Ferrum phos. (D6), Hepar. sulph. (12C), Verbascum (3X), Sambucus nig (3X), Lactose (inactive).

Directions for use: Give your cat 1 tablet or 2 sprays 3-5 times daily for 10-15 days. Continue for 3-5 days after the desired effect has been achieved. Safe for animals of all ages, pregnant animals or animals that are nursing. ProsPet can safely be used along with prescription medications. No adverse interactions have been noted between the ingredients in ProsPet and prescription medications. However, as with any medicine, it is always advisable to consult your vet.

Available in a bottle of 180 tablets, or a 2-fluid-ounce oral spray bottle.

Because Respo-K is 100% homeopathic, it supports the animal's body on a cellular level – getting to work upon the first dose. Within a few doses, the respiratory system is supported. Continued improvement will be seen with regular use. While some animals need only a single dose, others may require additional doses, depending on factors such as the age and size of the animal. Response times vary from animal to animal, based on physiological composition and other circumstances. While some animals begin to show an almost immediate improvement that increases over time, others will see results after 3-5 days. For long-term support of the immune system, PetAlive Immunity and Liver Support is recommended.

We're a small business, founded by a genuine old maid cat lady who loves her cats the same as if they were her children, just like you do yours. All products are shipped directly to you from our suppliers; we don't maintain any inventory. This eliminates double shipping, warehousing and staffing that would drive up costs, allowing us to price our items as reasonably as possible. When it comes to shipping, we charge you only what our suppliers charge us to ship the items to you. Those retailers who offer you "free" shipping are only raising their prices to cover the cost of shipping, and we'd rather be honest with you about it. If our suppliers include shipping in the prices of the items, we offer the same to you. We try to treat all our customers the way we'd like to be treated ourselves, and appreciate your taking the time to get to know us a little.
