Do Rabbits Really Love Carrots?

Rabbits and carrots go together like bears and honey. Bears really do love honey, but most people know that they like to eat more than just that (picnic baskets, for example).

Rabbits also enjoy a whole variety of food, but unfortunately some people think they can live exclusively off carrots. In reality, bunnies don’t eat root vegetables in the wild, so things like carrots should only be an occasional treat. The RSPCA found that 11 percent of all pet rabbits have tooth decay as a result of hitting the orange stuff too hard.

So if rabbits don’t eat carrots in the wild, where did the idea come from? Most blame Bugs Bunny.

While many thought Bugs got the habit from his furry peers, he actually adapted the carrot munching from the King of Hollywood, Clark Gable. Creators Chuck Jones, Friz Freleng, and Bob Clampett have explained that Bugs' trademark love of carrots was inspired by a scene in the 1934 film, It Happened One Night. In it, Gable's character leans against a fence and eats a carrot while explaining the rules of hitchhiking. In 1940, Bugs Bunny made his debut in a cartoon called "A Wild Hare," and exhibited similar behaviors:

At the time, the movie had just come out so the satire was likely obvious to viewers. Today, most children have never heard of Clark Gable and attribute the carrot eating to normal rabbit behavior. If you have a pet rabbit, read up on the proper foods to feed it—carrots are like candy for rabbits, so they should be given in moderation!

What Is the Shelf Life of Donated Eyes?

Zoe-Anne Barcellos:

I can only answer for cornea and eye donation.

The FDA does all oversight (no pun intended) of organ disposition.

The main organs—heart, liver, pancreas, lungs, etc.—are transplanted within hours. They are just not viable if they are not being perfused constantly.

The other tissues—like bone, skin, tendons, etc.—do not need to be transplanted immediately. But I am not sure on the regulations of when they need to be transplanted.

With the eyes, there are four tissues that can be recovered.

We recover whole eyes for research and education purposes. These usually go much faster, but we can hold them up to a year.

Conjunctiva can also be recovered; conjunctiva is a clear covering over most of the eye (it is what gets irritated when you have pink eye). I have been working as a recovery tech for five years, and our office has not had a request for "conj" in all that time. I believe it is mostly used for research, but I could be wrong.

Sclera is the white area of your eye. It is fairly thick and flexible. If you have ever touched a reptile egg, that is what it reminds me of. We recover sclera for transplant. They use it for several things, but mainly to patch punctures. Similar to if you pop the inner tube of your bike and repair it. Sclera can also be used to repair ear drums. We can hold on to this for up to a year.

The main thing we recover is corneas. In the U.S., we must transplant these within seven days of recovery. (Recovery is usually within hours of death, but we can push it up to 20 hours after if needed.) Sometimes we have more corneas than we need, and then they are shipped overseas and transplanted up to 14 days after recovery. There is no real different outcome with the later transplant time, but the FDA in the U.S. made the rules. (You can sign up to be an organ, tissue, and eye donor here.)

Why Are There No Snakes in Ireland?

Legend tells of St. Patrick using the power of his faith to drive all of Ireland’s snakes into the sea. It’s an impressive image, but there’s no way it could have happened.

There never were any snakes in Ireland, partly for the same reason that there are no snakes in Hawaii, Iceland, New Zealand, Greenland, or Antarctica: the Emerald Isle is, well, an island.

Once upon a time, Ireland was connected to a larger landmass. But that time was an ice age that kept the land far too chilly for cold-blooded reptiles. As the ice age ended around 10,000 years ago, glaciers melted, pouring even more cold water into the now-impassable expanse between Ireland and its neighbors.

Other animals, like wild boars, lynx, and brown bears, managed to make it across—as did a single reptile: the common lizard. Snakes, however, missed their chance.

The country’s serpent-free reputation has, somewhat perversely, turned snake ownership into a status symbol. There have been numerous reports of large pet snakes escaping or being released. As of yet, no species has managed to take hold in the wild—a small miracle in itself.
