The safest way to transport your cat is to calm them down.The new Mikki Calm Cat Muzzle works by stopping your cat from being able to see what is around them. This is often the best way of calming a cat, as they become quiet and are not threatened by every thing they see.The muzzle should only be used for transportation purposes and should not be left on the cat without supervision.Size: Small (kittens and small cats)
