I could not believe it worked so well.
I almost turned my cat into an outdoor cat due to stress urination. After one week with a diffuser, the urination completely stopped!
★★★★★
She's Finally Relaxed.
My biggest worry was that it would flatten her personality. She's exactly the same cat, same attitude, same energy — she's just not stressed anymore. The spraying stopped in about ten days.
★★★★★
I stopped blaming myself.
She wasn't broken and I hadn't ruined her. She just needed something to tell her the new place was safe. Within three weeks she was sleeping on the couch again.

Of Stressed Cats Get No Help
Multi-pet homes and rescues are the biggest triggers, leading to fights, scratching, and litter box accidents. Once stress takes hold, it's hard to undo.
If your cat is peeing outside the litter box, scratching furniture, or getting into territorial fights, it's mostly experiencing severe stress.
This issue needs to be addressed before it worsens over time.

You've Probably Tried These Solutions… But They Don't Work
Adding More Litter Boxes
While useful for multi-cat homes, extra litter boxes won't fix stress-driven marking. Many owners add boxes only to find their cat still peeing elsewhere.
Other Pheromone Diffusers
Generic pheromone diffusers don't combine both mammalian and maternal pheromones. Summit Calm+ uses both simultaneously for a stronger, faster calming effect.
Enzyme Cleaners
Enzyme cleaners remove the smell but not the stress causing the behaviour. Your cat will keep marking new spots until the underlying anxiety is addressed.
Changing the Type of Litter
Litter preferences matter for hygiene but have nothing to do with territorial stress. Changing litter rarely stops stress-driven spraying or fighting.
Separating Cats in Different Areas
Temporary separation reduces incidents but doesn't resolve the territorial tension. Once reunited the same patterns return — the anxiety is still there.
Don't Rehome Your Cat
Your cat isn't misbehaving — they're struggling with stress. They need you to address the real issue: their anxiety.
Summit Calm+ targets the root cause, helping you and your cat live in harmony.

No more stress...
I was having issues with my cat peeing outside her litterbox. We thought it might be related to her being stressed because of our dog. We tried the cat diffuser and no issues since. And the dog and cat are getting along better than ever!

Frequently Asked Questions
How long before I see results?
Most owners notice a shift within 2 weeks — less hiding, fewer incidents, a slightly calmer baseline. Full behavioural change typically settles in over 30 days of continuous use.
Is it safe around my kids, dog and other pets?
You won't smell anything — the pheromone is completely odourless to humans. It's drug-free, non-sedating, and safe to use around children, dogs and other pets. It only communicates with cats.
I tried Feliway spray and it didn't work. Why is this different?
Feliway spray wears off within 2–4 hours. By 3am when your cat's stress peaks, the effect is completely gone. The diffuser runs continuously, 24 hours a day, for a full 30 days on one refill. Most people who say "Feliway didn't work" were using the spray.
Will this work on a very anxious cat?
Actually, the worse the anxiety, the better the fit. The diffuser asks nothing of your cat — she just has to breathe. You don't need her to trust you yet. You just need to plug it in.
Should I unplug it at night?
No. Your cat's stress actually peaks at night, often around 3am. Unplugging it removes the signal at exactly the wrong time. Leave it running continuously.
