I bought a Lesser 800 grams 2 months Ago, I couldnt get her to eat. I tried everything, Mice, Rats, Live, Prekilled, etc. A month went by and she finally ate some live mice. I bundled up a ton of newspaper and put it in her tub, and dumped a few mice in there. When I checked back she ate. This wasnt Ideal for me because i dont have constant supply of mice, but I breed rats. So a few weeks later I tried to get her on rats with no Luck. I cleaned her tub and puts lots of extra newspaper in her tub and balls of newspaper, put in a weaner rat and bam she ate again. I am very relieved, so if anyone has the problems Ive had, try the paper trick, its working for me.
