I don’t think my bun is overweight, i’ve been following the suggested feeding recommendations and amount. Also last month I went to the vet and she came in at 5.5 pounds and the vet checked off the box that said “average”
Due to my work schedule, I’m only able to have Flospsie out of her cage for excercise about 3 hours a day (excluding petting and grooming time).
two questions:
1. When she is not roaming and exploring, she is in her huge x-pen (its actually two x pens joined together, literally half of the living room). She has ample toys or games or things to do. Her favorite thing is to chew cardboard and go into “Hulk destructo” mode 
However, after a short while, especially if i’m not there watching. She’ll just lie down. I know that she’s relaxed, but it seems a bit too relaxed. Is this normal? Or is she a bit lazy. There are literally so many things for her to do, but she just lies there.
2. When I let her out to explore, I have to closely monitor her. I don’t really bother her but i prevent her from getting into trouble. Sometimes she lives to run around especially down the long hallway. After running around a bit she will lie down. When she lies down her whole body is shaking. Her heart is beating fast and sometimes I can even hear it since shes close to the ground. Her body is shaking and her ears are twitching. I know that their hearts beat fast but its literally going crazy. The thing is, if she isn’t running around, even if she just is causally playing when she goes to lie down her ears are shaking too. Is this normal? Is she out of shape?
Thoughts?
