why do cats run like BADUNK BADUNK BADUNK
and in stairs like DUNKDUNKDUNK
It's because cats are technically a non-newtonian fluid. The more force they are under, the more solid they become. You can see this in action when you try to put a protesting cat into a carrier or when you see them melt in relaxation.
While they are running on the stairs, gravity is putting more force on them, which makes them more solid. Therefore, they get a bigger DUNKDUNK sound compared to normal running.
4 Ways a Male Cat Can Be Tricolor
The X chromosome in cats determine their fur color. This gene has two alleles, one for orange fur (XB) and one for black fur (Xb). Females carry two X's and males carry one X, allowing female cats to have two colors while restricting male cats to one. Therefore, it is extremely rare for calico males to exist!
Klinefelter Syndrome (XXY)
Male cats with an extra chromosome (X)
Allows for the expression of both orange and black pigments
Infertile
Extra X chromosome interferes with sperm production
Chimerism
Two embryos fuse together early in development, leading to a single individual with cells from both embryos
Allows for tricolor pattern in males
Sometimes fertile (depends on if the combination affected the reproductive organs)
Only one of their colors will be passed on to offspring
Mosaicism
Individual cat has two or more genetically different types of cells within their body
XXY cells and XY cells found in the body
Sometimes fertile
Only one of their colors will be passed on to offspring
Birthmark
Might be a patch of a different color or shade on the skin or fur
Does not result in a true tricolor pattern, but still causes variations in fur color
Fertile
Birthmark color does not affect offspring color
CATURDAY CAT FACT
When a cat sits down on you or next to you and seems to purposely face away from you, it might be because, in a cat colony, they position themselves facing away from each other so they can watch for threats.
So your kitty isn’t insulting you by showing you his butt. He’s protecting you.

It's only about 30min and it is very calming and informative. Also the research regarding older cats' kidney failure problem had funding issues — and cat owners around Japan stepped up and donated $2mil to help fund it! And honestly if they opened it up to the world I bet they'd be flooded with donations from cat owners, esp those who have already lost kitties to kidney failure
Despite being still fairly feral at thirteen years strong, my boy Casper the orange tabby floof displays multiple traits of domestication: bold white markings, long exquisitely soft hair, and an orange coat which would only ever rarely ever occur in the wild. Also, allergies.
There Was Another Domestic Cat!
I hate that I'm only now in 2024 learning about this rad 2016 cat science find (frustrating that it wasn't more publicized,); there's evidence in China that there was once a second species of domestic cat, Prionailurus bengalensis, or the Asian Leopard Cat. Fellow cat nerds will recognize that this is the same wild species that was hybridized with the domestic cat to produce the famously active and beautiful breed known as the bengal cat, however these ancient domestic cats evidenced in the study share no relation to the modern bengal. Modern domestic cats notably descend from the African wildcat (Felis silvestris lybica.)
The evidence of the domesticated version of the Asian Leopard cat is primarily wear patterns on teeth still connected to jaw bones found in China which do not show up in fully wild kitties. This basically means that these domestic cats were eating a diet which their wild brethren do not consume.
To me, the idea of a second ancient species of domestic cat is extremely intriguing and I will most definitely need to draw a concept if what these cats would have looked like with the calling card bold white markings and other domestic traits which inevitably appear in domesticated animals, as shown in the Russian Silver Fox Project which eventually produced completely domesticated foxes. It would also be very interesting scientifically to see the full ancient domestication of the Asian Leopard Cat reproduced although with thousands of modern domestic kitties in need of homes this experiment is likely never going to happen (which is for the better with so many far more suitable modern purr machines available for adoption.)
Domestication of modern domestic cats (Felis silvestris catus/Felis catus) likely took place on the Mediterranean island of Cyprus some 10,800 years ago with the cats quickly spreading to Egypt and China where they became beloved fixtures of temples, homes and palaces. Today thanks to artificial selection these kitties exist in miriad beautiful breeds and coat patterns but more importantly, modern kitties are noble, affectionate, and extremely social companions of the educated, responsible human household.
My three year old blue tuxedo cat Keplar, who spends his days playing, following me around everywhere that he can (getting very frustrated when he cannot,) chatting with me, and snuggling with his thirteen year old unrelated fluffy orange tabby brother, Casper. With a dilute gene turningwhat would've been a melanistic coat grey and bold white markings which are found only in domesticated animals, Keplar is an excellent representative of the modern domestic cat.
Following that post where you mentioned your cat responded to your mom despite having no previous relationship with her, it reminds me of this video (remember to turn on the subtitles):
https://youtu.be/QdzggIE29wo?si=QtB54m8mWjma2ev_
The tldr of the vid above is a cat owner pulled a deliberate prank on her 5 cats, she invited a female friends who looks similar to her and let her friend pretend to be her. In the end, only 2 (technically 3) cats out of 5 figured it out. Cats aren’t particularly good with eye sight so your cats might just distinguish you via your voice. :D
I have several thoughts on this, and because I take cats too seriously I have to say the women in the video didn't prove anything. The cats acted like normal cats who are given food by a friendly human, there was no experiment design here with "If the cats believe the impostor to be their owner, they will do X. If they correctly identify the impostor, they will do Y", instead there was only reading into their body language.
I think, if you want to know whether cats can identify people based on sight alone, the best approach would be an eye-tracking study (it should be doable on cats provided a cooperative cat and the right type of equipment) where the cat was provided with audio of its owner and other humans speaking, and images on the screen, and then you see where the cat fixates.
As it happens something similar has been done: cats learn the names of their friend cats, a study conducted using eye-trackers: meaning the stimuli provided to the cats was visual, so they had to recognize their friend cats from sight alone. (Not that this was the point of the study)
In other news, my cat (who I love )who was staring right at me when he thought I was in another room is just dumb.
when you accidentally end up with a special needs kitty and their special needs attribute is that they never learned to properly cat
this little shit is the most affectionate little kitty i ever met, ever since we earned her trust. it took a while, but once we got her flea problem under control, she was just so grateful for the relief, and she knew it was our doing somehow, so she decided we were her people and that was that.
she's also low-key fascinating in terms of what she does and doesn't do. i think maybe she was rejected as a kitten or couldn't latch, or maybe she was the runt of her litter. something happened to her that kept her from learning to be a cat, or that seems like the most likely explanation.
she was outside for who knows how long, and she knows what other cats are and may want to be their friend. we plan on getting a kitten at some point because we think it will be good for her. but the fact is, we don't know anything about her or why she's the way she is. she was probably supposed to be bigger; her growth was probably stunted, maybe because she got separated from her mom too early or was otherwise not able to get enough to eat at that point. at least she's spayed so we don't have to worry about that.
she also has a sensitive tummy. she doesn't scratch the furniture, which is good, but she doesn't scratch anything and so her claws are super sharp. so when she got fleas a little while back, she was scratching herself so much with those sharp claws that she was hurting herself. it's interesting to me as a phenomenon, as a scientific thing, but mostly i just want my little girl to be happy and healthy, and there's a bit of a learning curve on both sides, i suppose.
I was zoom chatting with my niece and nephew and the 9 year old asked « if O’Malley wasn’t a cat, what would he be? » (I adore little kid questions like this!! So out of the box and mind opening!) and at first my adult brain was like LOL he’s a cat what else could he be. But after just a second i instantly knew to answer « African grey parrot. » because this cat wants so much to be able to communicate complex things to the humans he would be over the moon about the ability to speak.
Like for example, two of the other cats in the house I would consider normal cat communication (the fourth cat has shared custody of a single brain cell and gets it on every other weekend. I love him and his empty skull dearly.) like they can communicate complaint, contentment, and demand, and you have to play a guessing game like « food? Walk outside? Pets? Did someone close a door? » Ect.
But O’Malley has the most diverse array of meows of any cat I’ve ever had, and understands enough human speech that you can have actual conversations with him. He has specific meows for asking where each member of the family is (well, one for each cat, mom, and then one for « where are humans? » for everyone else)
Like this (words between * are distinct meows he uses consistently. Italics are human words I know he understands so I say them slowly to him):
O’Malley: *where is apricot?*
Me: he’s downstairs honey
O’Malley: *thank you* (heads downstairs)
-————
O’Malley: *where is Harold?*
Me: in the living room
O’Malley: (heads to living room)
-————
O’Malley: *where is toy?*
Me: under the dresser
O’Malley: (heads to dresser, sticks his paws under and tries to get it out. Fails, sits up and looks at me) *help*
-————
O’Malley : *MOOOOOOMMMMM*
Me: in here baby!
O’Malley: (trots into room) *want*
Me: want what?
O’Malley: *want food*
Me: not now you just ate.
O’Malley: *NOOOOOOOOO* (dramatically flops on floor)
(I swear he must have picked this one up from the people because his « extreme displeasure » noise actually sounds like he’s saying « NOOOOOOO » lol)
-————
Me: (moves furniture around in the house)
O’Malley: (comes in the room) *NOOOOOO* (walks up to each moved item) *why* *why* *why* *why*
Me: it’s ok honey. It’s ok.
O’Malley: (hops up on my lap) *why?*
Me: (gives an explaination I’m sure he doesn’t understand but he seems to understand that I tried to tell him why.)
O’Malley: *i don’t like it* (this is a much smaller sound similar to the NOOOOO meow but he doesn’t seem to expect me to fix the problem with this noise, he’s just expressing himself)
-————
O’Malley: (hops up on windowsill) *SNOW!*
Me: yeah? (He understands this to mean « tell me more » and he usually adds more sounds to express himself)
O’Malley: (looks at me) *excited!*
Me: yeah?
O’Malley: *outside!*
Me: not now. I’m working now.
O’Malley: (sits down) *i don’t like it*
Me: I know. Later. Go play with a toy.
O’Malley: (long pause) *i don’t like it* (hops down and goes and gets his toy)
-————
O’Malley: *mom*
Me: (waking up)
O’Malley: *MOM*
Me: yeah?
O’Malley: *help*
Me: with what?
O’Malley: *sick*
Me: (sigh) did you puke
O’Malley: *help*
(He uses the *sick* meow any time he feels bad- if he’s about to puke, or did puke, or if he’s too cold or too hot or got bit too hard by another cat and it hurts later(he comes to show me his booboo and says *sick*) and he also uses it to alert me that Harold(who has digestive issues we are trying to sort out with the vet) pooped outside the litter box, which might be me reading too much into it but it seems like he is demonstrating an awareness that Harold is sick?? Like some form of empathy in putting himself in harolds place and understanding that diarrhea means Harold feels bad? That seems like a surprising amount of dots to connect for a cat but I’m trying not to underestimate animal intelligence until proven otherwise)
Vetblr and cat science people, have you seen a lot of this? I’m super curious to know how common this is. Out of the 13 cats I’ve had in my life this is the only one that communicates so clearly and consistently. Does he just have a wider range of sounds so I can understand him, and we as humans are just too deaf to understand the variation in other cat’s meows? Are my other cats trying to say this much to me and I’m just stupid?
