1 00:00:01,800 --> 00:00:04,320 Speaker 1: Welcome to brain Stuff, a production of I Heart Radio, 2 00:00:06,559 --> 00:00:11,080 Speaker 1: Hey brain Stuff, Lauren Bola Bam Here. Cats do all 3 00:00:11,160 --> 00:00:14,280 Speaker 1: kinds of stuff we don't understand, sometimes it seems like 4 00:00:14,280 --> 00:00:19,119 Speaker 1: on purpose, including licking humans. Dogs have more of a 5 00:00:19,120 --> 00:00:23,560 Speaker 1: reputation for being social, goofy, and lacking a nuanced concept 6 00:00:23,600 --> 00:00:26,920 Speaker 1: of personal boundaries. Cats are generally thought of as being 7 00:00:26,960 --> 00:00:30,520 Speaker 1: more standoffish and less prone to slobbering all over their 8 00:00:30,600 --> 00:00:34,520 Speaker 1: human compatriots. But every once in a while, your cat 9 00:00:34,600 --> 00:00:37,319 Speaker 1: will lose that sense of boundary and begin licking your 10 00:00:37,360 --> 00:00:41,880 Speaker 1: face or arm with that scratchy tongue, begging the question why. 11 00:00:43,680 --> 00:00:46,160 Speaker 1: For the article, this episode is based on How Stuff Works. 12 00:00:46,200 --> 00:00:49,440 Speaker 1: Spoke by email with Anita Kelsey, a cat behaviorist and 13 00:00:49,560 --> 00:00:52,640 Speaker 1: author of the book Let's Talk About Cats Conversations on 14 00:00:52,720 --> 00:00:56,840 Speaker 1: Feline Behavior, and she said cats explore the world as 15 00:00:56,880 --> 00:01:00,240 Speaker 1: kittens through their mouths and by chewing on things. They 16 00:01:00,280 --> 00:01:03,520 Speaker 1: lick to groom themselves and lick other cats, a behavior 17 00:01:03,560 --> 00:01:08,280 Speaker 1: called alo grooming in order to bond and groom. Cats 18 00:01:08,319 --> 00:01:11,360 Speaker 1: have a huge number of scent receptors compared with humans, 19 00:01:11,480 --> 00:01:15,520 Speaker 1: about two million compared to our measly five million, so 20 00:01:15,800 --> 00:01:19,240 Speaker 1: scent plays a big part in their everyday lives. Cats 21 00:01:19,280 --> 00:01:22,479 Speaker 1: can smell in two different ways. First, they sniff through 22 00:01:22,480 --> 00:01:26,240 Speaker 1: their noses in short, fast inhalations that capture the scent 23 00:01:26,319 --> 00:01:28,800 Speaker 1: molecules and hold them in a chamber in their nasal 24 00:01:28,800 --> 00:01:31,600 Speaker 1: cavity to let all of their sent receptors do their work. 25 00:01:32,520 --> 00:01:35,800 Speaker 1: A second, cats can taste and analyze scent through an 26 00:01:35,880 --> 00:01:38,240 Speaker 1: organ on the roof of their mouth called the Jacobson's 27 00:01:38,319 --> 00:01:42,199 Speaker 1: organ or the Eva Marionasal organ. When they're using this organ, 28 00:01:42,520 --> 00:01:45,279 Speaker 1: they make a weird face, sort of an open mouthed 29 00:01:45,319 --> 00:01:49,800 Speaker 1: grimace that scientists call a flame in response. This looks 30 00:01:49,800 --> 00:01:53,240 Speaker 1: to us like they're expressing distaste or disgusted, but they're 31 00:01:53,240 --> 00:01:55,800 Speaker 1: really just directing air towards the roof of their mouth. 32 00:01:57,760 --> 00:02:00,320 Speaker 1: Because most of a cat's face is involved in the 33 00:02:00,360 --> 00:02:03,400 Speaker 1: activity of smelling, it makes sense that a cat would 34 00:02:03,400 --> 00:02:05,920 Speaker 1: lick you in order to get more information about you. 35 00:02:06,760 --> 00:02:10,639 Speaker 1: But more than that, cats lick who they like, and 36 00:02:10,800 --> 00:02:14,680 Speaker 1: Kelsey said, cats lick us as a sign of closeness, bonding, 37 00:02:14,720 --> 00:02:17,640 Speaker 1: and affection. It's a form of grooming us, as they 38 00:02:17,680 --> 00:02:20,560 Speaker 1: do with other cats that they've bonded with. I'm sure 39 00:02:20,560 --> 00:02:24,160 Speaker 1: they're also enjoying taking in our scent. They love armpits, 40 00:02:24,200 --> 00:02:28,760 Speaker 1: for example, as there is a strong scent there. Although 41 00:02:28,800 --> 00:02:31,960 Speaker 1: cats aren't as exuberant in their demonstration of affections as 42 00:02:32,000 --> 00:02:35,880 Speaker 1: dogs usually are, according to Kelsey, we shouldn't compare the 43 00:02:35,919 --> 00:02:39,600 Speaker 1: two animals. She said, we are seen as part of 44 00:02:39,600 --> 00:02:43,360 Speaker 1: the cat family. Cats show us affection through behaviors like 45 00:02:43,480 --> 00:02:46,400 Speaker 1: remaining in our company, purring, sleeping next to us and 46 00:02:46,560 --> 00:02:51,280 Speaker 1: on our laps, and rubbing against us. Aside from a 47 00:02:51,320 --> 00:02:54,400 Speaker 1: cat's general affection for you and the urge to groom, 48 00:02:54,400 --> 00:02:57,440 Speaker 1: a buddy, cat might lick you for a variety of 49 00:02:57,480 --> 00:03:01,640 Speaker 1: other reasons. For starters, If your cat is regularly coming 50 00:03:01,680 --> 00:03:04,440 Speaker 1: at you with its sand paper tongue, the reason might 51 00:03:04,440 --> 00:03:07,399 Speaker 1: be that it wants to mark you as its territory, 52 00:03:07,600 --> 00:03:09,720 Speaker 1: and what better way to tell other cats to back 53 00:03:09,760 --> 00:03:13,680 Speaker 1: off than by smearing you with a little special spit perfume. 54 00:03:15,200 --> 00:03:18,440 Speaker 1: Cats also tend to lick things that they think are tasty. 55 00:03:18,800 --> 00:03:22,040 Speaker 1: Cats can't taste sweet things. They're the only mammal that can't, 56 00:03:22,480 --> 00:03:25,120 Speaker 1: but they might really like your hand, the lotion or 57 00:03:25,160 --> 00:03:28,640 Speaker 1: the residue that breakfast left on your fingers. If you 58 00:03:28,639 --> 00:03:31,359 Speaker 1: find that your cat is particularly interested in a specific 59 00:03:31,360 --> 00:03:35,360 Speaker 1: cosmetic product or appointment you use, especially a prescription ointment 60 00:03:35,440 --> 00:03:38,200 Speaker 1: like a hormone cream. Ask your vet whether it's safe 61 00:03:38,200 --> 00:03:42,680 Speaker 1: for them to ingest. Some cats also lick in order 62 00:03:42,680 --> 00:03:46,320 Speaker 1: to cope with stress or fear, and this behavior is 63 00:03:46,400 --> 00:03:48,800 Speaker 1: especially common in cats who were taken away from their 64 00:03:48,840 --> 00:03:51,600 Speaker 1: mothers very early, but it can happen in any cat. 65 00:03:52,440 --> 00:03:55,160 Speaker 1: If this behavior seems to worsen over time or is 66 00:03:55,200 --> 00:03:58,920 Speaker 1: accompanied by nervous body language, or if they begin over 67 00:03:58,960 --> 00:04:02,360 Speaker 1: grooming themselves to the point of creating bald spots, it's 68 00:04:02,360 --> 00:04:06,160 Speaker 1: a good idea to ask your vet about treatment. But 69 00:04:06,440 --> 00:04:09,920 Speaker 1: what about when licking is too much for you. It's 70 00:04:10,080 --> 00:04:12,360 Speaker 1: very sweet that your cat likes you but wants to 71 00:04:12,440 --> 00:04:14,720 Speaker 1: keep you clean or wants to tell other cats that 72 00:04:14,800 --> 00:04:18,200 Speaker 1: you're their person, But sometimes the licking can get to 73 00:04:18,240 --> 00:04:22,039 Speaker 1: be too much, especially because those little carratin barbs on 74 00:04:22,080 --> 00:04:26,839 Speaker 1: their tongue called pepilli, can hurt. Cat tongues are scratchy 75 00:04:26,920 --> 00:04:29,040 Speaker 1: because they need them to act as a brush for 76 00:04:29,160 --> 00:04:33,640 Speaker 1: combing fur and dislodging dirt, dander, and fleas. The papilli 77 00:04:33,760 --> 00:04:37,839 Speaker 1: are really effective tools because they're stiff, shape, wick saliva 78 00:04:37,920 --> 00:04:40,680 Speaker 1: off the tongue and onto the cat's fur for ease 79 00:04:40,720 --> 00:04:45,359 Speaker 1: of grooming and body temperature regulation. Researchers have even designed 80 00:04:45,400 --> 00:04:48,880 Speaker 1: better cat brushes based on the analysis of these barbs, 81 00:04:48,880 --> 00:04:54,040 Speaker 1: but they can definitely wear on sensitive skin. To dissuade 82 00:04:54,080 --> 00:04:56,680 Speaker 1: your cat from licking you, you can try distracting them 83 00:04:56,680 --> 00:04:59,400 Speaker 1: with a toy of getting out of brush and grooming them, 84 00:05:00,000 --> 00:05:03,320 Speaker 1: simply walking away, or even just putting a cardboard box 85 00:05:03,360 --> 00:05:05,919 Speaker 1: in the middle of the floor. It's worth a shot. 86 00:05:10,839 --> 00:05:13,279 Speaker 1: Today's episode is based on the article why does my 87 00:05:13,360 --> 00:05:15,719 Speaker 1: cat Lick Me?
