If your mouse is too fat, than it's either pregnant, has too much fat in the diet (sunflower, safflower & linseeds will make them fat, along with nuts) or there's a genetic problem that is causing them to be fat (like lethal yellow).
If your mouse is getting fat and is starting to nest that means she is pregnant. and is getting ready for her babies.
getting fat.
9 of the 10 fat-tailed mouse opossums (not the Paraguayan Fat-Tailed Mouse Opossum), the Fat-Tailed Dunnart, the Fat-Tailed False Antechinus, and 4 of the 5 pygmy possums (not the Mountain Pygmy Possum) are mouse-like marsupials that store fat in their tails.
Too much food, not enough exercise, too many sunflower seeds or junk food. Solution? Feed only what your mouse will eat in 30 minutes, add a wheel, & feed them more veggies & fruit.
That depends how fat the mouse is. lol.
If she's "...getting fat..." - either she's pregnant or you are feeding her too much food !
Because your feeding it too much smart one!
Well, no. Eating too much and getting too little exercise will cause you to gain weight.
