Your dog won’t stop pacing at night. Your cat turns into a trembling ball of fur the moment a thunderstorm rolls in. You’ve looked into CBD for pets, but the market is crowded, the claims are loud, and the last thing you want to do is waste money—or worse, give your animal something that doesn’t hold up to scrutiny.

That’s exactly the situation that pushed us to put Penelope’s Bloom CBD for pets under the microscope. This is a brand that’s built a quiet but loyal following among dog and cat owners who prioritize ingredient transparency over flashy marketing. After four weeks of hands-on testing, a deep dive into their lab results, and side-by-side comparisons with top competitors like Honest Paws, here’s what we actually found—no hype, no filler.

In this review, we’ll walk you through product quality, pricing, lab transparency, and how Penelope’s Bloom stacks up in the real world. Let’s get into it.

What Is Penelope’s Bloom?

Penelope’s Bloom is a pet-focused CBD brand specializing in full-spectrum and broad-spectrum hemp extract products formulated specifically for dogs and cats. The brand positions itself as a premium option in the pet CBD space, with a consistent emphasis on sourcing transparency, third-party testing, and species-specific formulations that account for differences between feline and canine physiology.

The company was founded with the mission of helping pet owners explore natural wellness options for their animals—particularly for everyday challenges like occasional stress, restlessness, and comfort support. Penelope’s Bloom sources from U.S. hemp farms and publishes batch-specific third-party lab reports (Certificates of Analysis, or COAs) for every product.

Their primary differentiator is the marketing around “pet-specific formulations”—the claim that their products are meaningfully tailored to cats versus dogs rather than being a single formula split between two labels. It’s a compelling angle, and we’ll address how substantive that distinction actually is as we go.

Penelope’s Bloom Product Range for Cats and Dogs

Penelope’s Bloom keeps their lineup focused rather than sprawling. Here’s what they currently offer:

CBD Oil for Pets
– Available in 500mg, 1000mg, and 1500mg strengths
– Full-spectrum hemp extract with MCT oil as a carrier
– Separate formulations for dogs and cats (the cat version uses a lighter concentration option and a milder flavor profile suited to feline taste sensitivity)
– Dropper-style bottles for precise, adjustable dosing

CBD Treats for Dogs
– Soft chew format—easier for older dogs or picky eaters
– Available in chicken and peanut butter flavors
– 5mg or 10mg CBD per treat
– Marketed for daily use as a consistent dosing method

CBD Capsules for Dogs
– Pre-measured dosing eliminates guesswork
– Available in 10mg and 25mg per capsule
– Vegan capsule shells
– Unflavored—a practical option for dogs with dietary sensitivities or food allergies

The range is modest compared to some competitors—there are no topicals, no specialty blends, and no cat-specific treats. That said, a focused lineup isn’t a weakness by default. It signals a brand that has chosen to do a few things well rather than dilute its attention across a broad catalog.

Our Hands-On Review

We tested Penelope’s Bloom’s CBD Oil for Dogs (1000mg full-spectrum) and CBD Soft Chew Treats over a four-week period with three volunteer pet owners and their animals: two dogs and one cat.

Product Quality & Packaging

The oil arrived in a dark amber glass bottle with a glass dropper—a meaningful detail, since UV light degrades cannabinoids over time. Plastic bottles are cheaper but a step down in quality. The label is clean, easy to read, and includes a QR code that links directly to the COA for that batch. The treats came in a resealable kraft pouch—utilitarian, but it does the job of keeping moisture out.

Taste & Compliance

Does your pet actually want to take it? This matters more than most reviews acknowledge.

The oil has a mild hemp flavor. Two of the three dogs took it directly from the dropper without issue. The third required it mixed into wet food—a common workaround that works fine and doesn’t affect efficacy. The treats were enthusiastically accepted by both dogs, though that’s a low bar; most dogs will eat a soft chew regardless of what’s in it.

The cat owner found the cat-specific oil had a noticeably milder scent than the dog version—relevant because cats are far more scent-reactive than dogs. Her cat tolerated small doses mixed into wet food, though without any particular enthusiasm. That’s a realistic expectation for most cats.

Observed Effects

We’re being precise here: we can report only what the pet owners observed during the testing period, not clinical outcomes.

• Both dog owners reported noticing that their pets appeared calmer in high-stress situations—specifically vet visits and a local fireworks event—beginning around weeks 2–3 of consistent use.
• The cat owner described her typically anxious cat as “seeming less on edge” in the evenings. The changes were subtle but consistent across the testing window.
• No owners reported any adverse effects, including lethargy, digestive upset, or changes in appetite.

Four weeks with three animals is a limited sample. These observations are informative, not definitive. Individual results will vary based on your pet’s weight, metabolism, baseline anxiety level, and how consistently the product is administered.

Lab Testing & Transparency

We reviewed the published COAs directly. Penelope’s Bloom uses Anresco Laboratories for third-party testing—a well-regarded, ISO/IEC 17025-accredited lab with a strong track record in the cannabis and hemp space. The test results we reviewed matched label claims within acceptable variance ranges (typically ±10%). The full-spectrum products showed expected cannabinoid profiles, and the batches we examined returned clean results for heavy metals, pesticides, residual solvents, and microbial contaminants.

This level of transparency is not universal in the pet CBD market. Many brands either skip third-party testing entirely or use in-house testing that carries obvious credibility limitations. Penelope’s Bloom clears this bar clearly.

One note: the broad-spectrum version marketed for cats should, by definition, test at non-detectable THC levels. Confirm this on the specific COA for the cat product before purchasing, particularly if your veterinarian has flagged THC sensitivity as a concern.

Pricing and Value

Penelope’s Bloom is priced at the premium end of the market:

Full-spectrum extraction is genuinely more complex and costly than broad-spectrum, so the price premium over broad-spectrum alternatives is defensible. The treats carry an expected convenience markup—that’s industry-wide, not a Penelope’s Bloom-specific issue.

Where value becomes a judgment call is the pet-specific formulation angle. If species-tailored dosing and formulation matter to you—and there’s a reasonable case that they should—then the pricing is in line with other premium pet CBD brands. If you’re skeptical that the cat and dog versions are meaningfully different beyond concentration and flavor, you may find better per-mg rates elsewhere without sacrificing much.

Penelope’s Bloom vs. Honest Paws: Quick Comparison

Honest Paws is one of the most visible brands in pet CBD and a natural point of comparison:

The bottom line on the comparison: Honest Paws has more product variety and broader taste appeal. Penelope’s Bloom has a stronger, more deliberate cat product and edges ahead on full-spectrum formulation consistency. For households with cats, Penelope’s Bloom is the clearer choice. For dog-only households where variety and flavor options matter, Honest Paws is the stronger competitor at a comparable price.

Pros and Cons

Pros:
– ✅ Verified lab transparency — COAs from an accredited third-party lab, batch-specific and publicly accessible
– ✅ Species-specific formulations — Separate products for dogs and cats, not a one-size-fits-all approach
– ✅ Full-spectrum extract — Broader cannabinoid profile than broad-spectrum alternatives
– ✅ Clean ingredient list — No artificial colors, flavors, or unnecessary additives
– ✅ Flexible dosing formats — Oils, treats, and capsules cover different administration preferences
– ✅ No adverse effects observed — No reports of lethargy, digestive issues, or appetite changes in testing

Cons:
– ❌ Premium pricing — Costs more per mg than several comparable brands
– ❌ Limited product range — No topicals, no cat-specific treats, no specialty wellness blends
– ❌ Hemp flavor resistance — A subset of dogs will need oil mixed into food rather than taken directly
– ❌ Cat treats absent — Cat owners are limited to the oil format only
– ❌ Subscription discount underwhelms — 10–15% off is below the 20%+ offered by several competitors
– ❌ No sample or trial sizes — Committing to a full bottle at this price point is a significant ask for first-time buyers

Final Verdict

If you’re looking for a pet CBD brand that takes formulation seriously, publishes verifiable lab results, and puts genuine thought into the difference between a cat’s needs and a dog’s, Penelope’s Bloom earns its place at the top of the shortlist. This isn’t a brand coasting on packaging and marketing claims—the lab transparency is real, the ingredient quality is solid, and the species-specific approach is more considered than most competitors bother with.

It’s not perfect. The price is steep, the product range is narrow, and cat owners will wish there were more formats to choose from. But in a market where cutting corners on testing and sourcing is common, Penelope’s Bloom does the fundamentals right—and that matters when you’re making decisions for an animal who can’t advocate for themselves.

Best for: Cat owners, multi-pet households, and anyone who won’t compromise on lab transparency or full-spectrum quality
Consider alternatives if: You’re working with a tight budget, you have dogs only, or you want a wider product selection
Best product to start with: The 1000mg CBD Oil—better per-mg value than the 500mg, and a more manageable commitment than the 1500mg if you’re new to pet CBD

Frequently Asked Questions

Is Penelope’s Bloom CBD safe for cats?
Penelope’s Bloom formulates a dedicated cat product and publishes third-party lab results for it. That said, always consult your veterinarian before introducing any new supplement to your pet—particularly if your cat is on medications, since CBD can interact with certain drugs metabolized by the liver.

How long does it take to see results with Penelope’s Bloom?
Based on our testing and owner feedback, most pet owners noticed observable changes within 2–3 weeks of consistent daily use. Some pets respond sooner; others take longer. Variables like body weight, individual metabolism, and the specific stressor involved all play a role.

Does Penelope’s Bloom contain THC?
Their dog products use full-spectrum hemp extract, which contains trace levels of THC at or below the federal legal limit of 0.3%. This amount is not sufficient to cause intoxication. Their cat formulation is marketed as broad-spectrum, which should test at non-detectable THC levels—verify this on the batch-specific COA before use. Penelope’s Bloom does not currently offer a CBD isolate option for pet owners who want to avoid THC entirely.

Can I use Penelope’s Bloom products for both my dog and cat?
We recommend using their species-specific formulations as intended. The concentration levels and flavor profiles differ for a reason—cats have different sensitivities and metabolic pathways than dogs, and what’s appropriate for a 50-pound dog is not the right starting point for a 10-pound cat.

Where can I buy Penelope’s Bloom?
Penelope’s Bloom products are available directly through their official website and select online retailers. [LINK: CBD pet brands directory] for a broader look at other options in the space.
