How do you know that these rats are 40 grams and how are you able to get the same size every time? Yes at 650 grams he should be able to take upwards of a 100 gram rat with ease. At this size I like to see mine eat every 10-14 days.
Like Mohegan said that it's not a race, but it's also not fun to under feed them so every time you place your hand in there they are grumpy and wish they could eat you![]()
