Published on 7/15/2008http://www.ehow.com/tips_4439055.htmland no, this live from 2-3 years.. <br/>why is this on EXPERT village?http://www.ehow.com/tips_4439055.htmlthey arent low maintenance..http://www.ehow.com/tips_4439055.htmlPlease do not listen to this one as much of her info is INCORRECT! Please visit www.pmgrattery.webs.com for accurate info on Rats. A Rex rat means curly or wavy fur and has NOTHING to do with the color. She also does not know the basic info of baby rats and she is sitting there breeding them! She says their eyes open at 6 weeks when they open at about 2 weeks. Also she says they start eating solid food at 6 weeks WHEN THEY START EATING SOLIDS AT 2 WEEKS ALTHO THEY WILL STILL ALSO NURSE UNTIL 5 weeks. She says the mom rat can get pregnant again at 6 weeks BUT SHE CAN GET PREGNANT RIGHT AWAY AFTER BIRTH! She also keeps the babies on WOOD shavings which is just unbearable to watch and can hurt the babies badly. Please, if you are a beginner do not listen to her as you can hurt ur rat and start off on the wrong foot. Please visit www.pmgrattery.webs.com for more accurate info or any other site online that is a breeder or a rat association...
