Fun fact: the sodium lauryl sulfate in toothpaste dulls the sweetness receptors on your tongue. The taste of orange juice after brushing your teeth is what it would ALWAYS taste like to cats.

> The taste of orange juice after brushing your teeth I'm always wondering how so many people know of this first-hand. Why are you drinking OJ, something extremely high in sugar, so soon after brushing your teeth?

Lots of people drink fresh OJ as part of breakfast.

Knowing this, when my cats desire something sweet that I was eating, I have always assumed they wanted something else they tasted in the food -- if ice cream, then the cream, etc.

Mine loves cantaloupe. I’m curious which part of that she likes other than the sweetness.

I also had a cat that went absolutely bananas for (especially ripe) cantaloupe. She could smell it across the house, would aggressively beg for it, and would purr the whole time she was eating it.

Some of the stuff I've seen our cat eating, it's both obvious and a blessing that he doesn't have much of a sense of taste. Goes nuts for the plastic wrappers you get around Pepsi cans and won't stop licking them. Little weirdo.

I have a cat who loves to lick crinkly plastic wrappers and bags. I use shopping bags for my bedroom trash can and I'll wake up to him just sitting there licking the folded over edge for upwards of 10 minutes. Two theories I've heard are that beef tallow is sometimes used in the manufacture of such bags so they might be smelling that. Or it could be as simple as they enjoy the sensation and/or sound of licking the ba…

Cats can be motivated by texture, so that may be part of it.

One thing I've noticed with cats in general is they seem to have a thing for human earwax. I'm not the only one to have noticed this: https://www.gwern.net/Questions#cats-earwax

.. Which I would expect people to eat before brushing, not after.

If you're really interested in cat nutrition, comment history of alleged veterinary student https://www.reddit.com/user/Pguin15/ is gold. He posted a link for example that shows cats and dogs readily digest carbs, and that this is well known: https://en.wikivet.net/Digestibility_of_Carbohydrates

> Ground, cooked and extruded starches are almost 100% digestible in both dogs and cats, while digestibility of raw (uncooked) starches varies from 0-65% depending on the type of starch.

> "This may be why cats are getting diabetes," Brand offers. "Cat food today has around 20 percent carbohydrates. The cats are not used to that, they can't handle it."

It's worse than that, usually 35-50% carbohydrates. The good (expensive) dry stuff is usually 10-20%. Wet food is often lower, depending on the type, as low as 7% as-fed with pates.

The weight-control labelled food is terrible both for weight and diabetes risk. It trades protein for carbohydrates under the assumption that cats don't absorb the carbohydrates as easily because the cat's liver has to process them. But this means the liver processes them to body fat, and the lack of protein leaves the cat less satiated, so it eats more food.

I've always been suspicious of that. Why is it specifically OJ that tastes awful, and not other juices, or chocolate, or bread?

You don't even need toothpaste. Taste is also a state of mind thing. Bet a friend/family member that they can’t taste the difference between whole/2%/1%/skim milk, or some combination thereof. Blindfold them and have them begin tasting the milks. Now, replace the last milk with orange juice. The brain prepares the body for milk, and the unexpected acidity usually causes a gag reflex, and sometimes vomiting. Keep a bu…

I found this out when asking myself the question "are animals fooled by artificial sweeteners". The rabbit hole that that led into is not only do we not know the answer to that question, many animals don't even taste "sweetness" (or if they taste it they don't like it or don't prefer it). Not even all primates, if I recall correctly. And we've seen drift -- apparently we used to be able to bait cockroaches with sweet…

Whoa. Smell was more important than sight for brain evolution? Is there somewhere I can read more about this?
