Kot Elvin by O.L.KAR. is a sterile aqueous infusion of medicinal herbs for cats: knotgrass, field horsetail, spotted lady's thumb and restharrow root. The manufacturer recommends it for prevention and as part of treatment for feline urinary syndrome and early-stage urinary stones, as the herbs have diuretic and anti-inflammatory properties. The pack contains 3 vials of 10 ml. For prevention, give 2–4 ml once a day for 5–7 days and repeat the course every 3–4 months. Important: with urination problems, see a vet and get a urine test first — a herbal remedy doesn't replace diagnosis.

Cons and what to keep in mind
- Doesn't replace diagnosis. Only a test shows the stone type (struvite or oxalate), and treatment and diet depend on it.
- No help with a blockage. If a male cat strains and no urine comes out, it's an emergency that needs a clinic, not drops.
- Contraindicated in acute kidney failure.
- Short shelf life once opened. With no preservatives, an opened vial keeps in the fridge for only 7 days.
Who it suits
At-risk cats — neutered, inactive, overweight, or with past cystitis — as support during preventive courses after consulting a vet. Signs, emergencies and diet are covered in urinary stones in cats. Prevention also needs water and the right food — read how much water a cat should drink. Prescription foods are in veterinary diets for cats, and other products in veterinary products.
Verdict
Kot Elvin is an inexpensive herbal remedy with a clear ingredient list that can be used in preventive courses and as part of treatment prescribed by a vet. Don't expect it to dissolve stones on its own: prevention rests on water, wet food, a healthy weight and regular urine tests for at-risk cats.
What else matters for prevention
Any drops work only together with the right lifestyle. Water comes first: add wet food to the diet and put several wide bowls in different rooms, or a fountain. Watch the weight and play with your cat every day, and keep the litter box clean so the cat doesn't hold it. Neutered cats do well on food with controlled minerals. Cats that have had problems before benefit from a urine test every 6–12 months.
