1Unscrew the Cap. That's It.
No plug, no batteries, no app. The gel starts releasing through the vented grille the moment the cap comes off, and keeps going for 60 days.

Another sprayed corner. Another load of laundry. Another night with one cat shut in the bathroom so the other one can eat. Both can be true. Neither is her fault. Or yours.
She isn't punishing you. She's telling you she doesn't feel safe.You've been treating four problems. It's one cat, in one state, showing it four different ways. Sivnv works on the state.

Enzyme cleaner removes the smell. It doesn't remove the reason. A jar near the spot works on why she marks it.

Two cats on edge in the same house will always find each other. Lower the tension in the room and the stand-offs get shorter.

You changed the litter, added a box, moved it twice. When it isn't the box, it's the stress.

New baby, new cat, new house. A jar where she hides keeps working, even when you're not home.
Not a different cat overnight. A cat who feels safe at home again, a little more every week.


You've already paid for the cupboard full of things that didn't work. Here's what's different this time.
Enzyme cleaners, new litter and extra boxes all deal with the puddle after it happens. Sivnv works on the stress that sent her there in the first place, 24 hours a day.

Separating them only pauses the fight. Slow reintroductions fail when the stress is too high. The gel lowers the tension in the room they share, so they can finally get used to each other.

No collar, nothing in her bowl, nothing on her fur. The gel stays inside the jar, behind a vented grille. Drug-free, not a sedative, odourless to you and undetectable to dogs and kids. She doesn't have to cooperate with it. She just lives in the room.

Plug-in diffusers heat the pheromone and degrade it on the way out, take a socket, stain the wall and need a new refill every month. One Sivnv jar runs cold for 60 days. Unscrew, place, forget.

Still skeptical? Good. Put it where the problem is and watch the next few weeks. Not calmer? Email us for a full refund. No return needed, keep the jars.

Sivnv is a pheromone-based calming aid for cats. It is not a medication or a veterinary treatment and is not intended to diagnose, treat, cure or prevent any disease. Individual results vary. If your cat suddenly stops using the litter box, see your veterinarian first to rule out a urinary problem.
Everything else on the shelf cleans up after the stress. Sivnv is in the room before it starts.

2Near the litter box. Where they clash. Where she hides. One jar per room, at your cat's nose height.

What's in the jar. Why it's different from what you've tried. And exactly how your 60-night money-back guarantee works.
That's the most common thing we hear, and it's the reason the gel exists. Electric diffusers heat the pheromone to push it into the air, and heat is what breaks it down. The gel releases it cold, around the clock. Many owners who decided pheromones "don't work on my cat" had only ever tried a heated plug-in.
Most owners describe the first shift in the first two to three weeks, and it's usually not "the problem vanished" but "she came out from under the bed." Give it the full eight weeks before you judge it. That's exactly what the 60 nights are for.
No. It's not a sedative, she stays exactly who she is. What changes is how safe she feels at home, and how she shows it. Most owners say they simply get their old cat back.
No. Nothing on her collar, nothing in her food, nothing on her fur. The jar sits in the room. She doesn't have to notice it, tolerate it or cooperate with it.
That's one of the situations it suits best, because it lowers the tension in the room they both share. Put one jar where they clash and one near the litter box.
Yes. The pheromone is species-specific: only cats perceive it. It's drug-free, fragrance-free and not a sedative. Safe for kittens from 8 weeks and senior cats, and it can be used alongside anything your vet has prescribed. Set it where it won't get knocked off.
One jar covers one room for 60 days. If it's only one spot, 1 jar is enough to start. But most cats show stress in more than one place: the litter box area, the room where they clash, wherever she hides. That's why most owners pick Buy 2 Get 1 Free (3 jars). Bigger home, several cats, or want spares for the next 60 days? Buy 3 Get 2 Free covers it all.
