You may be familiar with dogs sniffing one another to communicate in some form. However, have you ever seen cats sniffing one another? Turns out they do. There are some cats that will sniff another cat to communicate in some form of greeting of friendliness. Cats don’t sniff quite as quickly as dog though. When cats meet one another they tend to hiss and growl at first and then sniff each other’s faces and necks. This is the way they tell each other “hello.” Cats sniff the neck and cheek area because they tend to produce pheromones that signal friendship to other cats. Cats do not typically sniff the other cat’s rear until after they have spent some time around them and are more comfortable. Like dogs, cats are able to tell a lot about the other cat by sniffing his rear end. Learn more from your veterinarian Anderson IN.
