Outta My Box Soft Chews Supplement
Verified Jun 20, 2026
This is a soft chew supplement for both dogs and cats designed to support digestive balance and help make cat feces less appealing to dogs. It uses a proprietary ProBioStrive blend along with brewers yeast, flaxseed, and salmon oil in a palatable chew form. It’s intended for homes with both species, where dogs are getting into the litter box and you’d like extra GI support for both pets.
Overall, this is a specialized digestive supplement aimed at multi-pet households where dogs are eating cat stools, with ingredients geared toward GI support and stool odor control. The use of a proprietary probiotic/functional blend plus salmon oil and flaxseed is reasonable for digestive and stool-quality support. As with any supplement, it should be used alongside a complete, balanced diet and good litter box management, and it may not be necessary for pets without these specific issues.

At a Glance
KibbleLab Review
Strengths
- Formulated for both dogs and cats, which is convenient and helps ensure both species get the intended GI support in households with a litter box–raiding dog.
- Includes a proprietary ProBioStrive blend, likely representing probiotics or related GI-support ingredients, which can help maintain gut balance in some pets.
- Contains flaxseed and salmon oil, both natural sources of omega fatty acids that can support general health and gut function.
- Soft chew format is typically easy to give, especially for pets that resist powders or pills.
Considerations
- This is a supplement only and does not replace a complete and balanced diet for either dogs or cats.
- The key functional ingredients are in a proprietary blend, so exact amounts of each component are not clear, which makes it harder to predict how strong an effect any one part may have.
- Brewers dried yeast and “natural flavoring” can be problematic for a small number of pets with specific sensitivities, so it’s wise to monitor for any digestive upset or itching when starting it.
- Pets with pancreatitis, strict calorie needs, or very sensitive GI tracts should have any new supplement, including soft chews, introduced gradually and under veterinary guidance.

Top 5 Ingredients Explained
01
Proprietary Microbial Blend
A proprietary microbial blend is a formulated mix of live beneficial bacteria and/or yeasts included in pet foods or supplements to act as probiotics that support digestive health, nutrient absorption, stool quality and aspects of immune function in dogs and cats. Efficacy depends on the specific strains, viable CFU counts and product stability (many microbes are heat- and storage-sensitive), so owners should prefer evidence-backed formulations, follow dosing instructions, and consult a veterinarian before use—especially for young, elderly, immunocompromised animals or pets on antibiotics.
02
Brewer's Yeast
Brewer's yeast (deactivated Saccharomyces cerevisiae) is commonly used in dog and cat foods as a flavor enhancer and supplemental source of protein, B‑complex vitamins, trace minerals and immunomodulating components such as beta‑glucans. It can support skin, coat and general nutritional status, but may cause gastrointestinal upset or allergic reactions in yeast‑sensitive pets, is not a live probiotic, and should be used cautiously in animals prone to purine‑related issues or those receiving antifungal medications.
03
Calcium Sulfate
Calcium sulfate is an inorganic mineral used in pet foods primarily as a calcium supplement and as a firming or dough‑conditioning agent in treats and canned formulations. It supplies dietary calcium important for bone and muscle health in dogs and cats but must be balanced with phosphorus to avoid excess intake—especially in growing large‑breed puppies—and is generally regarded as safe when included at appropriate levels.
04
Potato Product
Potato products (such as flakes, meals or starch) are commonly used in pet foods as a digestible carbohydrate, binder and texture enhancer that contributes energy and palatability. They provide readily available calories and some minerals (e.g., potassium) and can serve as a gluten‑free carbohydrate alternative, but are high in starch and glycemic load—which may promote weight gain or affect blood glucose control in diabetic pets—and processing can reduce vitamin content; cats still require primarily animal protein despite tolerating some starch.
05
Flaxseed
Flaxseed is used in pet foods as a plant-based source of alpha‑linolenic acid (ALA) omega‑3, soluble and insoluble fiber, and modest protein, often added to support skin and coat condition, digestive health, and kibble texture; ground seed or flaxseed oil is more digestible than whole seed. Dogs can partially convert ALA to long‑chain EPA/DHA but cats convert ALA poorly and therefore still need marine sources for essential DHA/EPA; flax is calorie‑dense, prone to oxidation if not stabilized, and contains lignans (phytoestrogens) and trace cyanogenic compounds, so it should be processed and used in moderation.
