Ok will give him a small rat then, but last time he was losing weight pretty steadily despite eating a small one every week. they are 40 g, the small rats, mediums are 100 g
last week he took the medium one and has been in his hide instead of wrecking his tank while roaming and hasn't lost weight. he looked so skinny 2 weeks ago it was worrysome.
but am giving a small rat, will just have to buy some more if he loses weight again
