Hey, look a feature every mammal may need to evolve in the near future!
post
Still, that's pretty impressive. Cats are absolutely incredible animals. I'm thankful the "worst behaved cats" still love me for whatever reason because I've been able to see some of the crazy shit they do.
My parents have an entirely blind 18 year old cat. She can navigate the entire house eats fine, plays a bit. Hops up and down furniture, finds the sunbathing spots, uses the litter just fine. You do have to keep an eye out for her if your moving around as she can't smell fast enough if you step in front of her path.
I'm trying to imagine the world from this cat's point of view. Relying on smells, sounds, touch and vibration. I bet she can hear and smell small critters just fine, but would she be able to successfully hunt them?
She can still hunt rabbits somehow.
Not that they let her. They just discovered this by accident. She's an indoor cat that roams their high fence backyard when they're out there.
If the critter is close enough, their whiskers can pick up on vibrations in the air AFAIK, so they could probably still hunt.
please don’t go out of your way to give salt water to your cat
Advice to live by.
The fact that you need to tell people not to intentionally give their cat salt water is telling of how far we've regressed as a society.
Humans are naturally curious and lean towards the scientific method, that's why we always need a disclaimer, don't TRY this, they still will.
“Scientific method”?
Most people’s “method” is YOLO/HMB for lols. Thank goodness cats have nine lives.
Well, you know what they say about curiosity and cats...
They can drink salt water when times are tough but it still wouldn't be good to drink it for a sustained amount of time.
Don’t cats often die from kidney disease? :(
Yes, but often as a result of a long diet with chronic dehydration from a kibble based diet.
The moisture cats consume is from their prey. The blood and juices of rodents and birds hydrate cats.
Canned/wet food cats tend to wind up with thyroid issues instead of kidney. (Well, sorta: there's evidence the BPAs in cans and mercury from fish as a reason for that.)
Well this is partially true. I'm pretty sure even a cat on a perfect diet will still have very high chances of developing chronic kidney disease in old age because it is just common in cats.
Could be wrong but my understanding is that It's partially because their kidneys are so efficient that they often get kidney disease in late age. They're always under a super high workload.
yep, usually the first organ to fail in old cats, so the superpower seems to come with a drawback. edit: removed inaccurate statements
Old age, in and of itself, doesn't kill any living thing. There's always a system failure eventually. Seems like in cats that's commonly kidneys or thyroid.
They say the same thing about horses because of their kidney to body size ratio but it's simply not true. It might help them survive on saltwater longer than a human would but it's still a death march.
Evolutionary household cats are damn near perfection.
Not a crab
Penguins too but its in a supraorbital gland in their beak
like birds, they will probably eat your eyes first, which is mostly freshwater
I actually doubt it, they will probably stick to the cat food (not because it loves you or anything they are cold carnivorous predators but it is more familiar)they have left until the body is necessary and the eyes decay first so they would be gross by the time they got to them.
Probably about a week. Cats are desert dwellers, and your meat does contain water, which could buy them a few days.
Sort or related question, is that why their piss reeks like concentrated jenkem?
That’d be ammonia, a metabolic byproduct of their carnivorous diet.
Not trying to be that guy, but it's urea, which breaks down to ammonia due to microbial action once it's out of the cat. If a cat is pissing ammonia, it has big problems and needs to see a vet.
Other contributors to awful cat piss smell are mercaptans, the same compounds responsible for the scent of skunk spray, and pheromones and fatty acids released when the cat is spraying versus normal urination. It's all compounded by cats being adapted for arid environments so their urine is much more concentrated than human urine.
I love cats but they're gross little fuckers sometimes.
Dehydration is a common cause for cats to be 'ill' and brought to the vet,* so it could be that their piss reeks because they are having to concentrate it so much in the first place.
*source: a dimly remembered conversation with a vet friend when I asked her why she was adding water to the already wet food for her cat. She said her cat could never be encouraged to drink enough, so it was her way of staving off the annoyance of giving iv fluids to her own animal someday.
It's absolutely a thing, I've had several cats in my life look nearly on the brink of death before basically forcing them to drink or eat turned them around completely. They can be very stubborn. Fountains help a lot because in nature moving water is typically cleaner than standing water, so if your cat always refuses to drink, get a $10 cat fountain on Amazon, it works!
That makes sense, I wonder if it's the case and how common it is. I'll have to ask a vet tech that I know.
Isn't all Jenkem concentrated?
I'm under the impression that the basic product itself isn't a concentration, but more of a fermented brew.
we're going to need to evolve this superpower if we want to avoid my grandkids and your grandkids killing each other in the global water wars.
I could say that is an impressive evolutionary feat, but instead I'll say: Evolution, what the hell is wrong with you? You do know we all came from the sea, you should know 70% of the earth is covered in salt water, why did you think it was ok to devolve the ability to drink salt water but retain the requirement to drink water? Are you Ok? Do you need Jesus?
Evolution is considered a success if the animal lives long enough to successfully mate and nothing else matters to mindless evolution. At least cats don't have curly tusks that borrow through the skull if they live long enough like that infamous boar species I can't remember the name of.
kidney disease is one of the most common ways cats die of old age so super efficient kidneys dont come without a tradeoff. Cats have evolved to live in very arid enviorments where saltwater is all that is availible so the tradeoff might have been worth it. ability to drink saltwater only would work without kidneys being prematurely overstressed would be likely if animals had higher normal salt content but that would mean they would need a lot higher salt intake making living inland harder.
IDK man, whales can live over 200 years.
but whales like all sea creatures have high bodry salt content making the osmotic pressure difference small
Ok, so here's an Idea, have more salt in our fluids.
Great idea except we'd need another million years of evolution or more
No, you're missing the point again, when fish first went land diving they drank salt water because of that there body would have already had more salt and so would there kidneys, we evolved the ability to drink fresh water, that is what took a million years.
I didn't comment elsewhere but from this incoherent comment it's clear you don't have the first clue what you're on about, or why I said a million years (evolving a major change like sea to land takes hundreds of millions or billions of years).
Ideas are good, but people contributing ideas that show they don't know anything at all about the topic, while insisting they're right, gets tiresome.
if humans would be adapted to that it could work but it would mean without modern technology it would be close to impossible to survive without access to saltwater (most of human habitable land area)
Well we were already adapted for it or at least our ancient ancient fish ancestors were we lost the ability that's my core point, salt isn't exactly rare and other minerals can be used to reduce osmotic pressure, but besides that 40% of all people live near salt water and ~30% of all land animals live near salt water so I wouldn't think that would be enough to lose such a valuable resource as water, I am obviously wrong since we can't drink salt water but it still feels like a miss step.
i guess in the case of humans we would have evolved for a long time to mainly eat fruit that has a high water content with low salt content possibly even being most of needed water intake. after starting to eat meat perhaps there hasnt been enough evolutionary pressure to be able to regain saltwater consumption ability
