I think a large/XL rat would be anywhere from 150g to maybe 250,260g. When i do offer rats they are small, about the same size as a hamster. When I say large/XL rat, I mean thats what she should be eating instead of teddy bear hamsters as she is a little over 5ft. she's lost a little girth but is still overall looks very healthy
She is perfectly fine on a small rat once a week. She does NOT need large/XL rats, ever. As long as she isn't losing weight, she is fine.
