Juice for People; Not for Pets

Many items in our food pantry and garden can act as natural and dietary remedies for people and pets, and conventional medicines also have some carry over in differing doses. Parsley added to dog treats or salads can safely freshen breath for both species, and aspirin can soothe aches if not taken with certain other medications, nor where other counter-indications are present.

One of the latest questions is if the antioxidant juices people drink can be good for pets, even as a last resort. One question in particular is if Nopalea, which is made from the juice of the Nopal cactus, can be also used for canines and felines who are suffering from inflammation. Firstly, the Nopal cactus comes from the Opuntia family, more properly, Opuntia Ficus Indica. The Opuntia is a tree cactus. According to the ASPCA, Opuntia is nontoxic to dogs and cats. If a pet accidentally eats a small piece of the plant, the results might be prickly, but there will be no poisoning.

Although the plant itself does not pose a high toxicity risk, the juice itself is not formulated for pets. Cactus juice, which as a slight laxative effect, is not sold in its pure form. To be palatable, Nopalea juice includes other ingredients as well as supportive antioxidants. The other ingredients, and not the cactus juice, makes it potentially highly toxic to dogs.  The following is the list of Nopalea ingredients. Outlined in bold are ingredients helpful to humans but toxic, or possibly toxic to dogs and cats.

Proprietary blend of Water (filtered), Opuntia concentrate (nopal concentrate), Agave Nectar, Grape Seed extract (vitis vinifera), Raspberry extract (rubus idaeus), Strawberry extract (fragaria chiloensis), Cranberry extract (vaccinium macrocarpon), Apple extract (malus domestica), Apricot extract (prunus armeniaca), Mango extract (mangifera indica) fruit, Orange concentrate (citrus aurantium) juice, Papaya concentrate (carica papaya fruit with papain), Tomato concentrate (lycopersicon esculentum) fruit, Kiwi concentrate (actinidia chinensis), Guava (psidium guajava powder), Lemon concentrate (citrus lionum juice), Opuntia concentrate (nopal concentrate) powder, Peach concentrate (prunus persica) juice, Pomegranate extract (punica granatum with ellagic acid and punocaligans), Green Tea extract (camellia sinensis), Beet (beta vulgaris) juice, Bilberry concentrate (vaccinium myrtillus), Acerola cherry extract (malphigia glabra), Amylase, Cellulase, Hemicellulase, Proteases [bromelain from pineapple (ananas comosus) and papain (carica papaya) from papaya, lipase, phytase], Stevia extract (stevia rebaudiana) leaf, Guar gum, Maltodextrin, Natural flavor, Cherry powder, Xanthum gum.

  • Stevia can be upsetting to the stomach or even fatal to dogs.
  • Grapes are known toxins, which can cause hypercalcima, anorexia, lethargy and kidney damage.
  • Parts of the prunis family, such as the leaves, stems and pits are toxic. The prunis family includes apricots, peaches and cherries. The actual fruit is not toxic, but in the blending process, other pieces of the fruit could potentially intermix.
  • Healthy dogs produce their own Vitamin C. The jury is out on whether C supplementation is harmful or helpful, or may only be helpful in severely ill animals.

Before giving your pet a “home remedy,” note that their systems are not completely like ours. Read the ingredients very carefully. Not all products that do you good will do your dog or cat good, even if they are “natural.” Enjoy a glass for you, but don’t be tempted to give Mittens or Duke a sip.
