Ok...I am not quite sure how this happened, but I have an overweight mouse. My big boy isn't just big bellied...he is big all around..we call him "medium" as in reference to me one day saying he is as big as a medium rat. Sickle comes from the house of Fawn. He was raised with 1 brother, Darth Vader, and 5 sisters, Carrot, Beet, Moo-Latte--> his twin sister, Smokey and Bandit. Also there is aunt Turnip who helped raise the babies for Mama Fawn. OK.
None of the other girls are abnormally large, and Darth Vader is a runt so, I am not sure of where this jumbo mouse came from. His daddy Coal mouse, rest his soul, was a runt as well. I have had to purchase a hamster sizes wheel just so he can run without getting stuck. I have checked him again and again for any lumps or sign of disease. He is perfectly healthy.
To the best that I could, I weighed the hoss mouse and came to 35 grams = 0.0771617918 pounds. My beautiful baby boy playing in the hedgehog play-pen after mommy had already cleaned it out, sigh I am a slave to them all.
