Disclosure: La Petite Labs sells Pampered 90, a daily wellness system that may be relevant to some kin+kind supplement shoppers — both brands sell daily support formulas. It is not a substitute for kin+kind's grooming products, sprays, or veterinary guidance.
kin+kind Pros and Cons
Pros
- A named manufacturing location with open doors: US production disclosed at city-and-state level in New Jersey, with a public invitation to tour the facility — unique in our set.
- Real ingredient citations where most brands have none: the Hip+Joint curcumin-bioavailability claims link two live, publicly accessible NCBI/PubMed articles.
- Full active-percentage panels on the Flea+Tick spray line, printed on the product page.
- Evidence pages for ingredients, manufacturing, and the vet-formulated claim all sit one click away in a primary-header dropdown on every page.
Cons
- The Flea+Tick line's above-the-fold "CLINICALLY PROVEN FLEA & TICK REPELLENCY... Tested to deliver over 90% efficacy" claim has no visible study, author, or citation anywhere it appears.
- The veterinarian behind "vet formulated" and "designed by our own veterinarian" is never named or credentialed — including on the dedicated Vet Formulated page; the About page offers only a first name, Dina, for the founder side.
- No third-party laboratory, COA lookup, or contaminant/microbial/potency panel is disclosed anywhere; probes of common transparency-page handles came back empty.
- Label disclosure is uneven across the line: the sprays' percentage panels are the high point, and the supplement line doesn't consistently match it.
The Only Factory Tour in the Set
Manufacturing disclosure in this industry usually means the phrase "GMP facility" floating unanchored. kin+kind names the state, names the city context, and tells customers to come see it — "Join us for a tour of our facility in New Jersey" is language you can only print if the doors actually open. Pair that with a header dropdown that puts ingredients, manufacturing, and formulation-claim pages one click from anywhere, and two live PubMed links behind the Hip+Joint rationale, and you have the skeleton of a genuinely transparent operation — manufacturing 7 with a facility badge, rationale 7.
Proven, Says No One
The Flea+Tick claim is the sharpest internal contradiction in our expansion set. "CLINICALLY PROVEN FLEA & TICK REPELLENCY" with a specific number — "over 90% efficacy" — sits above the fold on both spray pages, and no study, protocol, author, or citation appears anywhere on the site to support it. This from the same brand that links NCBI articles for a curcumin claim. The capability to cite exists; the flea study either exists and is unpublished, or the claim is borrowing a register it hasn't earned. Either way, one email answers it.
The vet claim runs on the same fuel: a dedicated Vet Formulated page, a recurring "our own veterinarian," and no name, credential, or license anywhere. A brand that shows its factory can show its vet.
How to verify kin+kind yourself: ask for (1) the flea-and-tick efficacy study — design, n, and who ran it, (2) the formulating veterinarian's name and credential, and (3) your lot's COA with the testing laboratory named.
Public Transparency Score: 53/100
Under the 2026 Brand Transparency Rubric, kin+kind earns a 53/100 Public Transparency Score — Disclosure Gaps (scored as of 2026-07-03). The score measures what a buyer can publicly verify before purchase — labels, rationale, evidence, named experts, testing access, manufacturing disclosure, claim discipline, and findability. It is not an effectiveness score, a safety score, or a best-brand ranking.
The shape: manufacturing and rationale at 7 — carried by the named facility and the PubMed-linked logic — with labels, claims, and accessibility at 6, against evidence at 4 (real citations undercut by the uncited headline claim) and experts at 4 (a vet invoked, never named). Three badges earned, including the set's only disclosed-manufacturing-facility badge; five watchouts fired, led by the unnamed expert and the unmatched clinical claim. Naming the vet and publishing the flea study would put this brand near 60 overnight.
Best fit: natural-grooming households who value visible manufacturing and want the supplement line as an add-on. Keep comparing if: the flea-efficacy number is why you're buying, or you need named accountability and batch documents.
Owner Reviews and Price
The owner-review sample (38 items across 16 sources, checked 2026-07-03 — medium confidence) is small and calm: shipping (6) and owner-reported changes (5 — personal observations, not proof) lead, palatability trends positive, and the sample contains zero tolerance complaints. Prices checked 2026-07-03: Coat Spray $37.99; the grooming line anchors mid-market. Supplements are chew-dosed — compute per-day cost from your dog's serving count.
Where La Petite Labs Fits
The overlap is the daily supplement lane — kin+kind's Hip+Joint and daily formulas against Pampered 90 — while the grooming and topical-spray lines sit outside any comparison.
The ledger: kin+kind discloses the two things La Petite Labs also treats as non-negotiable — a real manufacturing story (theirs is more visitable: a named New Jersey facility with tours, versus La Petite Labs' country-level disclosure, said plainly) and real ingredient citations. Pampered 90's difference is completion: all 13 actives at per-active milligrams, per-batch heavy-metal, microbial, and potency testing by named labs (NSF and Eurofins) with a public COA lookup, and six named DVM contributors where kin+kind has an unnamed vet. Neither brand has a finished-formula clinical trial — La Petite Labs says so plainly, which is precisely what the flea-spray headline should also do.
Final Verdict: Should You Try kin+kind?
For the grooming line: comfortably, on the strength of disclosed percentages, a visitable factory, and clean support-framed claims. For the supplements: a reasonable pick pending one email — the label panels are uneven and the batch documents unpublished, from a brand transparent enough that both asks will land on a real desk in New Jersey. For the flea sprays specifically: do not buy the "90%" until you've seen the study, and remember that flea and tick control is a veterinary conversation with real disease stakes — essential-oil repellents, whatever their efficacy, are not a substitute for a vet-directed preventative plan.
FAQ
Is kin+kind legit?
Yes — a natural grooming-and-supplement brand with the only publicly tourable named facility in our 35-brand set, real PubMed citations on its joint line, and disclosed spray panels. Its gaps are an uncited efficacy claim and an unnamed vet.
Where is kin+kind made?
In New Jersey, at US facilities the brand names at city-and-state level and publicly invites customers to tour — the strongest facility disclosure we've scored.
Is kin+kind's flea spray clinically proven?
The pages say "CLINICALLY PROVEN FLEA & TICK REPELLENCY" and "over 90% efficacy"; no study, author, or citation appears anywhere on the site. Ask for the study before weighing the number — and keep your vet's preventative plan regardless.
Who is kin+kind's veterinarian?
Not disclosed. "Vet formulated" and "designed by our own veterinarian" recur, including on a dedicated page, without a name, credential, or license anywhere public.
What is in kin+kind Flea+Tick spray?
A printed active panel: peppermint oil 1.00%, rosemary oil 1.00%, cedarwood oil 0.20% — full percentage disclosure, the label high point of the line.
Does kin+kind cite any research?
Yes — the Hip+Joint line links two live NCBI/PubMed articles on curcumin bioavailability, real ingredient-level citations most competitors never provide. The flea claim carries none.
Does kin+kind publish COAs or name a lab?
No. No laboratory, COA lookup, or test panel appears anywhere, and probes of common transparency handles came back empty. Request your lot's certificate.
How much does kin+kind cost?
Checked 2026-07-03: Coat Spray $37.99; mid-market across the line. Supplements dose by chew count — compute per-day cost for your dog.
How does kin+kind compare with Pampered 90?
Both disclose manufacturing honestly — kin+kind more visitably. Pampered 90 adds the completion layer: 13 actives at per-active milligrams, per-batch named-lab testing (NSF, Eurofins) with public COA lookup, six named DVMs versus an unnamed vet. Neither has a finished-formula trial.
What should I verify before buying kin+kind?
The flea-efficacy study and its methods, the formulating vet's name and credential, your lot's COA and lab, and the specific SKU's label panel — disclosure varies across the line.
