A Matter of Animal Taste
Cats don’t have a sweet tooth … and other tasty facts.

Humans have up to 10,000 taste receptors on our tongues. But cows have more than twice as many. (And yes, it’s true that cats can’t taste sweet, but they do still like watermelon!)
Here’s some more info from Australian Broadcasting Corporation on what tastes like what to whom.
