| SUSHA FANCY RAT |
This is Susha. Albino young female rat. Male rats are over 800 grams, while female rats average 400-500 grams, with the smallest girl under 300 grams. Females have distinctly different personalities. Most male rats tend to be laid-back and more interested in staying on a lap for a long petting session, while female rats are explorers who love to play.
Training.

Answers.com - What is the IQ of a rat
"What is the IQ of a rat?
In: IQ [Edit categories]
I cannot give you an IQ number but I can tell you this. Rats are very, very smart. Fancy (pet) rat tend to be smarter than wild rats. Fancies can learn to:
Come when called
Identify basic shapes
Learn commands such as 'Sit up' or 'Kiss'
Play hide and seek with you on command.
Not leave the cage until told 'Out' or 'OK'
Not go back in the cage until told 'In' or 'OK'
Rats make wonderful pet. AND THEY WILL NOT BITE AT ALL (hamsters, mice and gerbils all will)
Finally, if your getting a rat please don't breed or buy while shelter rats die! Rescues are always socialized. Please go on Petfinder.com to find a small animal rescue in your area."

Scientists Produced Male and Female Mice from Two Fathers !!!

American scientists have created male and female mice from two fathers, using stem cell technology. The scientists say the achievement could help same-sex couples to have their own genetic children one day.
It also could help improving livestock breeds, preserving endangered species and advancing human assisted reproductive technology.
The study, led by Dr. Richard R. Behringer at the M.D. Anderson Cancer Center, was posted at the online site of the journal Biology of Reproduction.
The team of scientists in Texas manipulated fibroblasts from a male mouse fetus to produce an induced pluripotent stem cell line. The team says that about 1% of these iPS cells spontaneously lost their Y chromosomes, resulting in XO cells.
The XO stem cells were injected into blastocysts from donor female mice. The treated blastocysts were transplanted into surrogate mothers that gave birth to female XO/XX chimeras having one X chromosome from the original male mouse fibroblast.
“Our study exploits iPS cell technologies to combine the alleles from two males to generate male and female progeny, i.e. a new form of mammalian reproduction,” according to the authors.
The scientists point out point out that it’s possible ”one male could produce both oocytes and sperm for self-fertilization to generate male and female progeny.”
