If dogs and cats could talk, they’d debunk these myths! 1. Dogs eat grass only when they’re sick Research shows there are several possibilities why dogs eat grass — they might do it out of boredom, opportunity, or just because they like it! This is generally harmless as long as the grass is free of pesticides and your dog isn’t vomiting up what he eats. But if eating grass and throwing it up becomes a habit, there might be an underlying issue and you should get your dog checked out by a veterinarian. 2. Cats purr when they’re happy While this is true, it’s not the only reason cats purr. They use it as a self-soothing technique when they’re scared or sick. Mother cats will purr to comfort kittens, as well as use it to beckon them to her when it’s feeding time. 3. Dogs can’t see in color It’s long been thought that dogs only see in black and white. The truth is they can see in color, but they have fewer cone receptors — two out of the three that humans have. This means they see a smaller range of colors than humans. Studies show that dogs can see shades of yellow, blue, and gray, and some say their color vision is similar to red-green colorblindness in humans. 4. All cats hate getting wet Most cats don’t like water, but there are a couple of breeds that would be happy to jump in the shower with you! One such breed is the Bengal (pictured here). These cats love to play in water any chance they get, whether it’s getting into a bathtub, dipping a hand in an aquarium, or inspecting the water in a toilet bowl. Another water-loving breed is the Turkish Van. Nicknamed the “swimming cat,” this inquisitive breed with a water-resistant coat loves to play with faucets and take dips in the pool. 5. Dog and cat hair cause allergies It’s actually proteins from the skin, saliva, and urine that cause pet allergies. Dead skin cells (called dander) flake off your pet, get into the air, and settle in upholstery and carpet. Similarly, saliva and urine can collect in carpet, bedding, and other textiles. This causes an allergic reaction, with symptoms such as sneezing, watery eyes, and a runny nose.
