I dont go by body weight and never have for feeding. If you need to get rid of the Rats go ahead and give her both. If you dont need to get rid of them I would just feed her 1 then wait till the next regular schedule feeding day myself to get back on the right day. She will never notice the difference if she missed a meal 4 days ago or 3 weeks ago as you always feel her well. Sometimes I'll feed then 3 days later feed again if my days were off...
