KibbleLab Score
6.8 out of 10

This herbal liquid can be a reasonable add-on for owners who prefer a botanical approach to support relaxation in otherwise healthy dogs and cats. It combines several traditional calming herbs in a glycerin and water base and is dosed by body weight. As with any supplement, it should be used alongside, not instead of, a complete and balanced diet and good behavioral and environmental management for stress.

Nutritional Perspective

KibbleLab Review

Strengths

  • Uses multiple well-known calming herbs such as California poppy, valerian root, hops, passionflower, and skullcap, which are commonly used in veterinary herbal practice for relaxation support.
  • Liquid format with drop-based dosing allows fairly precise adjustment by body weight and makes it easier to give with food, especially for cats.
  • Free of common food allergens like chicken, beef, dairy, wheat, and soy, which is helpful for pets on restricted protein diets.

Considerations

  • This is a supplement, not a complete diet, so it does not provide essential nutrients and must be used together with a balanced pet food.
  • Herbal products can vary in how individual pets respond, and some sensitive animals may experience gastrointestinal upset or sedation, so starting slowly and monitoring is important.
  • Because herbs like valerian and hops can have sedative effects, this product should be used cautiously in pets on other sedative medications and is not meant to be given right before anesthesia, as the label notes.

Top 5 Ingredients Explained

01
California Poppy
California poppy is used in pet products as a botanical calming/herbal additive rather than a nutrient, included for its potential mild sedative and anxiolytic effects. Evidence for benefit in dogs and cats is limited, and it can cause drowsiness, gastrointestinal upset or interact with other sedatives or medications, so consult your veterinarian and avoid use in pregnant or medically fragile animals.
02
Hop
Hops (the flower cones of Humulus lupulus) are not used as a purposeful nutritional ingredient in pet food and do not provide recognized dietary benefits for dogs or cats. They are considered a toxic accidental contaminant—especially dangerous to dogs—because ingestion can trigger malignant hyperthermia, rapid breathing/heart rate, tremors, seizures and potentially death, so any exposure should prompt immediate veterinary attention.
03
Oat
Oats are commonly used in pet foods as a digestible carbohydrate and source of soluble fiber (beta‑glucans), plant protein, B vitamins and minerals, which can support healthy digestion and help moderate blood glucose and cholesterol. They are generally well tolerated by dogs and can be included sparingly for cats, but owners should avoid flavored or sweetened preparations (and ingredients like xylitol or raisins), be mindful of possible grain sensitivities or cross‑contamination with gluten, and prefer cooked oats for better digestibility and portion control due to caloric content.
04
Passiflora Incarnata
Passiflora incarnata (passionflower) is a botanical ingredient used in pet supplements and calming treats for its mild sedative and anxiolytic properties rather than as a nutrient; it contains flavonoids and alkaloids that are thought to influence nervous system activity in dogs and cats. While it may help reduce mild anxiety or promote relaxation, evidence in pets is limited and it should be used cautiously—avoid combining with other central nervous system depressants, and consult your veterinarian before use in pregnant or nursing animals or pets on medications due to potential interactions and dosing concerns.
05
Skullcap
Skullcap is an herbal botanical sometimes included in calming or joint‑support supplements for dogs and cats because its flavonoid compounds (e.g., baicalin) have antioxidant, anti‑inflammatory and mild anxiolytic effects. Evidence in pets is limited and products vary in potency, and skullcap can interact with sedatives or drugs metabolized by the liver and has been associated (rarely) with hepatotoxicity, so it should be used under veterinary guidance, especially in pregnant/nursing animals or those with liver disease.
