If your feeding once every 5 days and there is a small lump you should be fine for now. I didnt quite understand 1f 7" (1f 6"). Is that 1 female 7 inches long. and ATM I figured that is a mouse/food item..... If you upgrade to the next level go with a peach fuzzy. (about a 7 day old mouse, just getting it hair, but you can still see the skin.)
