I haven't been able to get her out to put her on a scale, but last time I weighed her was about 2 months ago and she was 900 I believe, she seems to have put on a lot of weight. Apparently the owner before me didn't feed her regularly so she's pretty small for her age, but she's put on a lot of weight since I got her. I can try to get her out and weigh her again tonight but I'm not sure yet. I thought about increasing the food size, but the rats I give her are slightly bigger than her stomach so I can't really go much bigger I don't think. I have a picture of her with a rat in her mouth and thr lady at the pet store said it looked too big for her.
