What it is intended for
FELIWAY Optimum releases a synthetic pheromone complex into the room. Owners commonly consider it during moves, introductions, urine marking, hiding, or tension between cats.
Improve the environment too
A diffuser works best as one part of a plan that includes enough litter boxes, separate feeding stations, hiding places, vertical territory, predictable play, and careful introductions. Plug it into an open outlet in the area the cat uses most.
Do not overlook illness
Urination outside the box, hiding, aggression, or appetite changes can have medical causes. Arrange veterinary assessment when behavior changes suddenly or the cat appears unwell.
Evaluate objectively
Choose two or three observable behaviors, record their frequency before use, and reassess after the recommended period. This is more reliable than judging from a general impression.
FELIWAY Optimum Diffuser FAQs
Where should FELIWAY Optimum be placed?
Use an open wall outlet in the room where the cat spends the most time. Avoid furniture, curtains, shelves, and strong drafts around the diffuser.
How long before I assess the result?
Use it continuously for the period recommended by the manufacturer and track specific behaviours. It is not an instant sedative and not every cat responds.
When should a veterinarian be involved?
Urinary changes, appetite loss, aggression, pain signs, sudden hiding, or persistent stress require veterinary assessment rather than only an environmental product.
