The genetic basis for fur colour in cats is well known (see link).
A sample of skin cells is taken from a cat fetus and gene splicing
techniques are used to replace the genes responsible for pigmentation.
This creates a series of cell lines each of which will grow fur of a
different colour.
As
the fetus develops, the recoloured cells are implanted into its
skin at carefully chosen locations based on the pixels of an image
file. The cells begin to divide as normal, eventually becoming patches
of fur of the desired colour.
Finally the fetus is reimplanted into its mother's womb and allowed to
grow as normal, eventually resulting in a healthy adult cat patterned
according to your image of choice.
The resolution and colour gamut of this technique will both be crude
compared to the method described in "Why Paint Cats?" (link) but this
idea offers the potential for a permanent design at far less risk to
the animal's health.
If successful, this approach could be extended to other mammals. It
could prove particularly valuable in farming for producing
individually bar-coded sheep and cattle.

I once tried for a Barking Zebra Rat here...
it didn't last long, but I am still convinced
of its possibilities. |
|
| |
Now a cat that glowed in the dark, like those piglets they GM'd not too long ago, would really be something to freak out the neighbors. |
|
| |
Wrong is my middle name! Well, er, first name. |
|
| |
As for glowing in the dark, I'm not sure today's genetic technology is capable of expressing arbitrary proteins such as GFP half way down the length of a hair. |
|
| |
Also, GFP will not make an animal glow in
the dark. The clue is in the name: green
fluorescent protein. It will shine under UV
light, but not glow itself. For that you need
a luciferin/luciferase system. |
|
| |
// far less risk to the animal's health // Hmm assuming it survives till birth I would imagine there's still a larger than normal possibility of malignancy. |
|
| |
Still, that wouldn't stop me ordering a mini tiger. [+] |
|
| |
Can't you print genes using something similar to an inkjet printer? If so, you could create a graft sheet that can then be applied to create a complex pattern. |
|
| |
I had a parrot. He said lots of things about me. |
|
| |
[-] for any pro-cat idea. |
|
| |
There could be much more elegant ways of personalizing. Pigmentation is brought about via a vast toolkit of genetic switches. By knocking out different varieties of switches at the onset of development, you could produce anything from zebra cats to fractal cats. At the very least this would simplify the process, as all this fetus transport isn't good for baby. |
|
| |
Are they black stripes on white zebras or white stripes on black zebras? |
|
| |
Great idea! If you combine that with the medical practice of inserting genes to cause the production of insulin, or some other bio-med product, you could have a label saying what the animal was producing growing on it’s side. [+] |
|
| |
//knocking out different varieties of switches at the onset of development// Would it really be feasible to create arbitrary images like this? |
|
| |
Presumably, one should gain access to most pigmentation patterns in the animal kingdom, and perhaps beyond if there remains untrodden territory from natural selection (which there probably is). But, completely arbitrary? No. No amount of genetic manipulation on the zygote will result in your maiden name spelled across your cat's ass upon maturity. I could be wrong, been wrong before. |
|

I'm a Tabby. A big Freakin' Tabby with big - well, you know what - their are Ladies here |
|
| |
My fur is my fur and get your stroopid genetal hands off it. Right? |
|
| |
Am I the only one with horrifying visions of cows grazing in a field next to a busy highway, thier broad flanks emblazoned with advertisements? This would be particularly disturbing should the farmer secure a contract with, say, Burger King. |
|
| |
Since the products of Burger King, McDonalds and the like contain only trace quantities of actual meat, and that often by accident, it wouldn't be that disturbing ... |
|
| |
//[-] for any pro-cat idea.// But [po] and [The Kat] seem to think this is really an anti-cat idea, so would you re-consider your vote on that basis? |
|
| |
I already have a perfect cat. He's big
and orange, never scratches the girls,
and kills the hell out of mice. His
natural pattern is part of his sleek
coolness, and his vertical darker orange
stripes make him look even bigger than
he is. |
|
| |
He's got big white paws that spread his
weight out when he jumps up to be
petted, and sharp, curved claws that
click on the floor when he walks. |
|
| |
We really don't need a cat to be
anything else. |
|
| |
// We really don't need a cat to be anything else // |
|

// re-consider your vote // |
|
| |
Yes. We will review the relevant comments and if necessary adjust our vote. |
|
| |
Not all people who hate cats are stupid.
But most stupid people hate cats. Most
people who hate cats are stupid, for that
matter. |
|
| |
In any case, there is a strong correlation
between stupidity and hating cats. And
between hating cats and insecurity, for
that matter. And general
dickheadedness. |
|
| |
Oh oh... Can I hate cats too?? |
|
| |
I had somebody challenge me to a drag race once and my answer was, "Sure. I have the rope, do you have a cat?" |
|
| |
Not at this moment, but we can get you one.... don't go away ...... back in a minute ..... |
|
| |
// Not all people who hate cats are stupid. But most stupid people hate cats. Most people who hate cats are stupid // |

Your statements are probably correct, but if you will forgive a descent into sophistry, the logic contained therein is flawed. |
|
| |
50% of the population are of below average intelligence (presuming a normal distribution). |
|
| |
"Most stupid people hate cats". |
|
| |
A lot of clever people hate cats too. Therefore we can conclude that the majorioty of the population, of whatver IQ, hate cats. |
|
| |
"Most people who hate cats are stupid" |
|
| |
This implies that people of lower intelligence are more likely to hate cats. No problem, as long as they are in the majority; this ensures, in a democratic system, a large popular vote for the "We all hate cats" party. |
|
| |
Ocne we are elected to power, we will use our legally obtained democratic mandate to suspend all democratic institutions, and focus all resources on putting all cats to death by fire and the sword. Swords dipped in paraffin gel will be issued to all stupid people along with a box of matches, a picture of a cat printed with "JKnow your Enemy", and a label on the hilt which indicates in pictograms to "hold this end". |
|
| |
Alternatively, we offer cats the opportunity to be repatiriated to their country of origin, by our hypersonic "cat cannon". |
|
| |
I would have made it a universal affirmative, but I was trying to be nice. |
|
| |
//repatiriated// says it all really! - he's a sad drunk who cannot spell and cannot see beauty in nature. so sad! |
