I have a mojave ball python that won't eat a certain mouse. I bought 6 mice for breeding and put them in a cage expect for 1 female, who already looked pregnant. I put her in a different cage so she could give birth (she looks like she swallowed a golf ball) 4 weeks passed. The other 4 females got pregnant and already had babies, which I am about to ween from their mothers. I fed the male to my snake. The 1 female that already looked pregnant, had no babies. She just stayed fat and gross. I have repeatedly tried to feed her to my snake but he has no desire to eat her. He has eaten every other mouse I have given him before and I tried a different mouse and he ate it. Shes fat, gross looking, now too old to use as a breeder, not appealing to my snake and just a gross stinky pain in my ***. Why won't he eat her?
