Dr. Elsey’s Respiratory Relief, sold as R&R, is a clumping clay litter with herbal essences. Chewy currently titles the same listing R&R Stress-Reducing, so you may see both names at retailers.
Dr. Elsey’s markets R&R Respiratory Relief as a low-dust clay litter with herbal essences for cats with respiratory issues. Litter does not treat respiratory disease, so follow your veterinarian’s guidance if your cat has breathing symptoms.
How Dr. Elsey’s Respiratory Relief Differs From Ultra
Both are unscented clumping clay with no perfumes or deodorants. Ultra lists natural clay as its only ingredient. R&R adds herbal essences, which Dr. Elsey’s positions as part of a calming litter box experience.
Our Dr. Elsey’s cat litter guide compares all five formulas.
What Reviewers Report
Dust. Most reviewers describe it as low dust. One reviewer who had tried several other low-dust litters, including corn, crystal, paper and wood, described R&R as lower in dust than those alternatives.
Clumping. Most reviewers report hard clumps that hold together when you scoop.
Odor. Reviewers report good odor control in single-cat and multi-cat homes.
Automatic boxes. One reviewer uses it in a Litter-Robot 3. Check your machine’s manual before switching, and see our guide to the best cat litter for automatic litter boxes for other options.
Possible Downsides
It’s clay, so the bag is heavy to carry and pour.
Some reviewers say it sticks to the sides of the box more than other litters, so full cleanings take more scrubbing.
Dust isn’t low for everyone. At least one reviewer called it the dustiest litter they’ve used.
Who It Suits
Best for: Owners who want Dr. Elsey’s hard-clumping clay with herbal essences added.
Skip it if: You want to move away from clay. Our natural cat litter and wood cat litter guides cover other options. For more low-dust choices, see our best cat litter for asthmatic cats guide.
Frequently Asked Questions
Will R&R help my cat’s breathing?
Litter isn’t a treatment. If your cat is coughing, sneezing often or breathing with effort, see your vet. If your cat is struggling to breathe, get veterinary care right away.
How much litter should I use, and how often should I scoop?
Dr. Elsey’s directions say to fill the box to 3 to 4 inches, scoop twice daily and add litter as needed.
Is there a silica gel version of Respiratory Relief?
Older Dr. Elsey’s materials described Respiratory Relief in both clumping clay and silica gel formulas. The current lineup lists R&R Respiratory Relief as clumping clay and Clean Air as a separate low-dust silica gel litter.
How do I switch my cat to R&R?
Check the bag first. If it gives no directions, set up a second box with R&R beside the old one so your cat can choose.
