My female weighed in at 795 grams on Dec 4th, that was 4 days adter feeding her a largish small rat. Today I weighed her and she's at 866 grams 2 days after feeding a rat aprox the same size. My mail weighed 492 grams on the 4th and is now at 605 grams after feeding on the 5th. Are these good weights for 2 days post feeding? Yes I am trying to put weight on both. They don't look underweight until you pop them on a scale. Thanks for advice.
