The vets explained that they are trying to tell people meowing cats
There is not a more effective sedative than the purr of a cat. But not always, this sound indicates that the animal feels comfortable. What I want to say we cats are your purr, explained veterinarians.
Experts have found that cats emit a vibration, not only when happy or satisfied, but when I feel pain or sorrow. This explains the purr in stressful situations like visiting the vet, but how to determine upset at this point, the cat or happy?
Experts suggest to refer to the appearance of the pet. If purring is accompanied by behavior that suggests that pet is uncomfortable (posture, in which the cat selects under itself legs and ears is short, like a decreasing in size), likely have a four-legged friend problem.
Purring in these moments — a completely natural process. Dr. Francine Rattner of veterinary clinics South Arundel (USA) noted that purring relieves pain in cats, reports The Daily Mail.
Other doctors compare purring with a smile people, because we smile not only when happy but when sad.
