You don't need a phd to know cats indeed fart. The times my cat has gassed the room with a silent toot...

Cowdoy_Volnutt | 17 hours ago

My kitten loves farting on us. Just silent whiffs while she innocently cuddles and we suffocate.

birdtripping | 14 hours ago

One of our cats always delivers her farts personally to my husband, as if bringing him a gift.

Are you kidding me?!

Yes they bloody well fart.

They fart like sailors !

Greendale_Official | 15 hours ago

Unless this is a quote and I'm not catching it, I've never heard my cat fart.

What kind of diet do your cats have? Mine are on a mix of Fancy Feast (wet food) and Iams (dry food).

seilrelies | 14 hours ago

They don’t possess butt flaps so their farts are silent but lethal.

Lower_Ad_1317 | 14 hours ago

This is true. And they just love showing that balloon knot don’t they. 🤷🏼🤦‍♂️🎈

Greendale_Official | 14 hours ago

Not exactly the scientific response I was looking for, but uh, thanks.

Butt flaps cause farts to make noise

E pluribus (cat) anus.

xenomorphling | 11 hours ago

Total misinformation, cats absolutely can and do fart audibly. They're inherently stealth-oriented animals, so they mostly do so quietly.

all you need to make noise anally is a sphincter and gas escaping. Do you shit silently? no. Are your butt cheeks clasped together while you dump? I'd hope not.

I'm sorry but I have it on the authority of GC, BWR, NW Princess Donut the Queen Anne Chonk that cats do not fart!

alasw0eisme | 2 hours ago

I do shit silently, actually. Not a sound.

Fireman's blanket?

alasw0eisme | 2 hours ago

idk what that means

MikeHuntSmellss | an hour ago

It's a tactic employed by shy poopers. Laying down a few sheets of toilet papper on the surface of the bog water to slow down the incoming turd and reduce the noise it makes.

MikeHuntSmellss | 2 hours ago

Same as dogs. Mine still wakes himself up farting

Lower_Ad_1317 | 14 hours ago

Yes they are on a mixed dry and wet diet. But you don’t always hear it. It isn’t always a disruptive “phlarp”. But it can be smelly.

When I have heard it, it was civilised, unremarkable, pushed out, but with an air of good manners.

I believe they don’t actually plan them but they just find their way out.

I can add detail but if you have a cat and you have never detected them doing it then you are missing one of natures greatest achievements.

To all intents and purposes the feline fart is the perfect fart.

Greendale_Official | 14 hours ago

Well that was informative. I don't know what I'll do with this info but I sincerely appreciate the write up. Godspeed and enjoy your depths of knowledge.

Lower_Ad_1317 | 14 hours ago

It’s not knowledge. It is experience my young Pandowan. 🤣

I've only heard my cats fart under certain conditions, like picking him up just as he lets loose, hilarious little poot.

pittakun | 10 hours ago

Mine do once a month aiming at my face, she is a princes

Material_Worth_4616 | 10 hours ago

Trust me the cat I had when I was a kid would STINK up my bedroom when I wanted to cuddle

I’ve also never heard or smelled my cats farts

General_Ad_2718 | 14 hours ago

Mine could clear a room.

Lower_Ad_1317 | 13 hours ago

Now you’re bragging.

But this is a thread about cats 🙄

😂😂😂👍

General_Ad_2718 | 13 hours ago

It’s hilarious to see my cat and dog on the couch and the dog will leave while side eying the cat like only a German Shepherd can. 10 pound cat wins.

[OP] scientificamerican | 20 hours ago

“Cats are farting all the time,” says Nick Cave, a specialist veterinarian at Totally Vets in Feilding, New Zealand, who has written about animal farts, including in the 2013 textbook Canine and Feline Gastroenterology. “They are passing gas.” Many other animals, including most mammals, snakes and some fish fart, too—although the jury is reportedly still out on spiders.

TheRadiorobot | 18 hours ago

You could hear them at our house all the time! Barking…

tommykiddo | 16 hours ago

I wonder if the cats farted into his arms?

seriouslyjan | 19 hours ago

If a dog farts, they own their own farts. If a cat farts they look at you and get mad at you for creating a stinky environment.

Put-A-Bird-On-It | 15 hours ago

I had a pitbull when I was younger, and when he was a puppy he ripped a loud fart. It startled him and made him jump, then he started barking at his ass. It was one of the funniest pet moments I've ever experienced.

Ariandrin | 19 hours ago

I have heard my cats fart, but they’re generally not too… odorous. The dog, on the other hand, is bad enough that I have erroneously blamed the boyfriend lol

DinkandDrunk | 19 hours ago

I’ve been around cats my whole life and I’ve only ever had one that could clear a room, but holy hell if that wasn’t the worst smell on earth.

BananaJelloXlii | 11 hours ago

My cat has IBS. Trust me, we know when he does

Ariandrin | 10 hours ago

Haha I have an IBD cat too. He’s not gassy but booooy his poops are nuclear.

Material_Worth_4616 | 10 hours ago

My grandmas cat is the same way… she does it when she’s nervous or excited

We’ll visit and she’ll just start farting

Drpoofn | 8 hours ago

My orange guy can clear a room. He audibly burps and farts.

BananaJelloXlii | 8 hours ago

Ours is orange too!

blipp1 | 17 hours ago

Do your bf eat dog food? With my 7 dogs in the past 20 years I've never had dog farts smelling like human farts.

rumshpringaa | 17 hours ago

Mine is allergic to chicken (dog, not husband) and before we figured it out, her farts would make your eyes burn

Ariandrin | 16 hours ago

It was when my dog has eaten something that she normally doesn’t. Like if she’s tried a new human food. Particularly broccoli lol

With just her kibble and her normal veggies, her farts are just little puffs of air with no smell at all lol

Greendale_Official | 15 hours ago

Small note, dogs can be allergic to broccoli: that all said broccoli causes gastric distress in most humans too.

Not suggesting that you were doing anything wrong, I just thought it was worthy of note.

Ariandrin | 14 hours ago

Oh she had like, a grape sized amount of broccoli and that was it, just to monitor her reaction to it before I considered adding it to her regular veggie rotation.

And she gassed us out three times on the 20min drive home after eating only that much lol. That was last Christmas, and she hasn’t had any since.

Greendale_Official | 14 hours ago

And again, I wasn't trying to drag you or anything. Broccoli makes my stomach go crazy.

Back in my "gym days" I was constantly unhappy with my stomach with the combo of broccoli and whey protein lol. Have you ever wanted to punch your own butt?...I may have revealed too much.

Ariandrin | 13 hours ago

Hahaha I feel that, but it’s not broccoli that does that to me, it’s Dairy Queen ice cream lmao

Not any other dairy source, not any other type of ice cream, only Dairy Queen. It’s the only thing where I need to take a lactase supplement or I am hating my life for the rest of the day.

So I always introduce new things in small amounts with my pup because I know I can’t handle tummy pain for shit, and I don’t want that for her either.

Also, she’s a pit mix, and already has a chicken sensitivity, so I am always on the lookout for some new food sensitivity to pop up because pits tend towards being… gastrointestinally delicate, I guess lol

I also have a cat with IBD, my delicate little babies

Greendale_Official | 10 hours ago

Oh hey! I actually think might have an answer for you. Do you know much about carageenan? It's a seaweed derived thickener that is in quite a few products.

Dairy queen uses it as part of their base for their soft serve. You might also note that the Lactaid brand milk also contains it (for some weird reason) and a lot of people with lactose issues complain about feeling sick after having it.

You should look into it!

Ariandrin | 9 hours ago

This is very interesting, I may have to investigate further!

Generally I just don’t eat it (healthiest option anyway lmao), but when I do, I take two lactaid and it’s usually fine, but I can’t say I haven’t been curious about why this happens!

gene66 | 17 hours ago

My cat farts all the time when I am around my wife. When we are separated he doesn’t fart at all. Curious.

dikicker | 15 hours ago

Lol I think your dude is gaslighting you

Source: I can be sneaky too

What, me? I would never! No, blame it on the dog!

Ariandrin | 14 hours ago

I’d probably think the same if she didn’t later gas me out without him in the room lol

dikicker | 14 hours ago

This made me laugh way harder than warranted, cheers friend

dankristy | 11 hours ago

Holy hell can we swap cats or something? I love our dapper Tuxedo boy (Clark W. Grizzwold - Grizz for short) but his farts are DEATH (as are his shits).

We have tried so many things and foods (even our vets just say he is a lovely stinky well dressed lil dude).

Ariandrin | 10 hours ago

My IBD cat has the stinkiest poops in the world, omg. He’s not gassy, but his poops are awful.

If you haven’t yet already tried it, I would try a food with hydrolyzed protein (usually from your vet). My poor IBD dude is much better on the vet food

Feline herpes leads to nasty smelling farts

Achylife | 14 hours ago

I assure you they do. Especially one cat my friend had when we were kids. She was like a walking stink bomb. Squeeze her at all and she'd let one rip bad enough to clear the room.

Beevershot | 14 hours ago

Same here! Friend's cat would toot each time you patted his rump. 😆

Stochastic-Parrot_13 | 18 hours ago

Yes they most certainly do, and they let rip some of the most eye watering stinkers of any mammal.

Kahnza | 20 hours ago

I remember a friend of mine's cat many years ago. On a special diet of some kind. But many times a day this incredibly foul stank would just creep through the house. 🤢

HauntingYam5815 | 17 hours ago

Having raised several kittens, I love witnessing their first audible fart, usually it startles/confuses them lol

Mudeford_minis | 16 hours ago

Yes. And they stink. But it’s like they have a sense of humour like humans, as in they drop one next to you and casually exit the room.

ph33rlus | 14 hours ago

Everything with a butthole farts. Cleared that up for you

Our cat is more of a hit-and-run farter - walks in the living room, farts, walks out, and leaves us to deal with the stench.

I used to have a kitten that would silently fart, and I only know that because it smelled so fucking bad. It seemed like she grew out of it eventually

DoctorGarbanzo | 16 hours ago

Yes they do. Years ago got the most adorable, teeny, tiny, kitten that emitted the most horrendous of farts.

Will2LiveFading | 15 hours ago

bejebers27 | 15 hours ago

My cat fartwd so loud that we both jumped!

diibadaa | 14 hours ago

My cat sometimes relaxes on my lap so much that he farts the most silent and smelliest fart ever.

tunalic2 | 14 hours ago

A friend of mine used to have a cat that he could squeeze and it would fart.

My deceased friend Dweezi used to fart occasionally. The room would suddenly smell like a cat box for a few minutes, then clear up.

My cat 13yrs farted while in my lap for the first time the other day. It reeked! Then I got worried and had to check her litter box in case she had diarrhea or something, she was fine….First time for everything!

Dogs fart because they are boys. Cats do not fart because they are girls.
