FELIWAY Optimum is a patented* pheromone discovery developed by the #1 vet recommended brand to help reduce common signs of stress in cats such as: scratching, urine spraying, conflicts between cats, and excessive hiding.
FELIWAY diffusers are drug-free, non-sedating, and have been used by millions of cat families to help ease cats’ stress related behaviors by sending them reassuring messages, similar to natural pheromones.
Our best solution, FELIWAY Optimum helps cats with more signs of stress, in more situations, and calms cats better than ever.
Cat owners reported more than a 70% reduction in scratching, urine spraying, conflict, and hiding when using FELIWAY Optimum.
FELIWAY is backed by over 25 years of feline stress expertise and scientific research.
The diffuser continuously releases calming pheromone analogs for up to 30 days, to help comfort your cat. Simply plug into an open outlet with 4+ feet of space to diffuse, with vents pointed upright.
Safe to use – while pheromone analogs may help your cat, they won’t affect humans or other pets.
