Are Cedar Chips Safe for Cats and Dogs? What Pet Owners Need to Know

Updated March 2026 — Written by the team at DoubleTree Forest Products, who harvest and process incense cedar in the mountains of the western USA.

If you're a pet owner looking for natural ways to repel fleas, freshen bedding areas, or add mulch to your yard, you've probably wondered: are cedar chips actually safe for my cats and dogs?

The short answer: yes — natural cedar chips and cedar shavings are safe for both cats and dogs when used as directed. But there are a few things worth knowing before you spread them around your home or yard.

Why Cedar Gets a Bad Reputation

You might have seen warnings online about cedar and pets. Most of those warnings come from two sources:

• Confusion with treated lumber. Pressure-treated cedar or cedar stained with chemicals is absolutely not safe for pets. We're talking about natural, untreated cedar — the kind that comes straight from the tree.
• Old studies on cedar shavings in enclosed spaces. Decades-old research on hamsters and small rodents in sealed enclosures showed that concentrated cedar oil vapors (plicatic acid) could irritate respiratory systems. But those were tiny animals in airtight boxes breathing nothing but cedar fumes. That's not how anyone uses cedar chips in real life.

For cats and dogs in normal household or outdoor use, natural cedar chips are not only safe — they're beneficial.

How Cedar Chips Help Your Pets

Natural Flea and Tick Repellent

Cedar contains natural oils — primarily thujone and cedrol — that insects hate. Fleas, ticks, ants, mosquitoes, and moths all avoid cedar. This is why cedar chests have been used for centuries to protect clothing.

Spreading cedar chips or cedar granules around your yard creates a natural barrier that repels fleas and ticks without any chemicals touching your pets. No sprays. No pesticides. Just wood that bugs can't stand.

Odor Control

Cedar naturally absorbs and neutralizes odors. If you've ever walked into a cedar closet, you know that clean, fresh scent. Cedar chips in dog runs, kennels, or outdoor pet areas keep things smelling fresh between cleanings.

Moisture Absorption

Cedar chips absorb moisture from the ground, keeping pet areas drier and reducing the conditions where bacteria and parasites thrive. A drier yard means fewer fleas, less mud, and a cleaner pet.

Cedar Chips for Cat Litter — Does It Work?

Some cat owners use cedar shavings or fine cedar chips as a natural cat litter alternative. Here's what to know:

• Pros: Natural odor control, biodegradable, no clay dust, pleasant scent, naturally antibacterial
• Cons: Doesn't clump like clay litter, needs more frequent changing, some cats may not like the texture initially

If you want to try it, use fine cedar chips or cedar shavings — not large bark pieces. Our cedar chips are hammer-milled and sifted to a fine, consistent size that works well for this purpose.

Tip: Mix cedar shavings 50/50 with your current litter for a week to let your cat adjust to the texture and scent.

Cedar Chips in Dog Runs and Kennels

This is probably the most popular use of cedar chips for pet owners. A 2-3 inch layer of cedar chips in a dog run or outdoor kennel provides:

• Natural flea and tick prevention
• Excellent drainage (no muddy paws)
• Odor control between cleanings
• Soft, comfortable surface for dogs to rest on
• A fresh cedar aroma that's pleasant for humans too

Replace or refresh the chips every 3-6 months depending on use. The cedar scent fades over time as the oils dissipate, which is your signal that it's time to add more.

What About Cedar Granules for Yards?

If your main concern is flea and tick prevention across your whole yard, cedar granules are the way to go. They're smaller than chips, spread more evenly, and release cedar oils into the soil as they break down.

Spread granules around your yard perimeter, under decks, around dog houses, and in any shaded areas where fleas tend to congregate. One application lasts 4-6 weeks depending on weather.

The best part: your kids and pets can walk on treated areas immediately. No wait time, no chemicals, no warning labels. It's just cedar.

Which Pets Should Avoid Cedar?

While cedar is safe for cats and dogs, there are a few exceptions:

• Small rodents in enclosed habitats (hamsters, guinea pigs, rabbits in indoor cages) — use paper-based or aspen bedding instead. The enclosed space concentrates the oils.
• Pets with known cedar allergies — rare, but possible. If your pet sneezes excessively or develops skin irritation after cedar exposure, discontinue use.
• Very young puppies or kittens — their respiratory systems are still developing. Wait until they're at least 8-12 weeks old before introducing cedar bedding.

Not All Cedar Is Created Equal

There's a big difference between the cedar chips you find at a big box store and what we produce at DoubleTree Forest Products.

Most commercial cedar mulch is made from eastern red cedar or juniper — which isn't technically cedar at all. Our products are made from genuine incense cedar (Calocedrus decurrens), harvested from dead and downed trees in the mountains. Incense cedar has a richer, more aromatic scent and higher concentrations of the natural oils that repel insects.

We don't add dyes, chemicals, or fillers. What you get is pure cedar, straight from the forest to your door.

The Bottom Line

Natural cedar chips and cedar shavings are safe for cats and dogs. They repel fleas and ticks naturally, control odors, absorb moisture, and make your yard smell incredible. Use them in dog runs, garden beds, yard perimeters, and even as a natural cat litter alternative.

The only pets that should avoid cedar are small rodents in enclosed habitats. For everyone else — spread it, enjoy it, and let nature do the pest control.
