December 17, 2007: Brave Mice
http://cellar.org/2007/Brave Mouse.jpg
Fear is all in your head! Or at least it is for mice. That's what the Japanese researchers at Tokyo University set out to prove when they created a new breed of genetically modified mice that are not afraid of cats. By turning off certain smell receptors in the brains of their mice, the scientists were able to show that their newly-ballsy mice are only instinctively afraid of the predators' smell, rather than learning from experience that cats will gobble them up. Alternatively, I suggest that they could design genetically odorless cats. Seems more useful in the long run to me. |
They've done the glow-in-the-dark cats so why not odorless?

I remember reading a story about this topic, and I think it was something about the smell of the cat's urine that triggered a fear reaction in the mice. As to the observation about the path to learning in the mice, how exactly would a mouse learn from experience that cats gobble them up. More to the point, how can the mouse communicate that learning to other mice?

Mouse makes a mistake around a cat, gulp, burp. Yep, sure can't see many mice making a cat-related mistake and having the opportunity to learn from the experience (assuming wild mice and wild cats). |

I reckon this beast ain't afraid of no cat neither!
Attachment 16234 The 1.4kg Mallomys giant rat is one of two species of mammal found by Conservation International on an expedition to the Foja Mountains in the north of Papua province, Indonesia. From the BBC. |
60 minutes went to the Foja mountains in a piece titled "Garden of Eden." It was nothing less than fascinating. Film clips may be found here.

Or, Mouse with sensitive nose and hates the smell of cat piss stays away from cats and lives to reproduce. Passing sensitive nose genes on to kids. |
Or, mice generally don't live alone--mouse watches brother get eaten by a cat, grief stays fresh in his heart and reminds him to stay away from the cat.

it would be advantageous for cats to lose their odor, if one subscribes to M. Pollan's "Botany of Desire" premise, right? non-stinky pee cats are likely to become a more popular pet than a stinky pee cat. and they'd prove better de-mousers, too. toxo was just trying to help the process but got the wrong beasie.

Feed them asparagus?

If you check out those pics you can be surprised
If you want to see ideal coexistence between a cat and a mice check this pics.
It seems like love is in the air. |
Welcome to the Cellar, Edna. :D
