Maybe she´s impact.. What substrate do you have her on?
If she´s impacted she´s surely dehydrated also.. If you don´t know how to check that.. You just lift up a little of her skin gently.. if the skin stays that way even if you don´t hold it up, she´s dehydrated.. YOU MUST TAKE CARE OF THAT!!! The easiest way is to go to the vet because it´s very hard to fix it yourself..
Put her in lukewarm water for about 20 min´s & gently massage her belly at the same time..
Another thing you can do if the first one didn´t make her poop..
Give her parrafinoil or any other oil you have home..
If this doesn´t work either you can fill up the bathtub with the hot water, put a char in it & her in a little box on top of the chair.. Leave her there for an hour..
I hope something of this works for you.. But first you must go to the vet if she´s dehydrated or else she won´t be able to get rid of the impaction..
If she´s not imapct I don´t have a clue of what it can be.. parasites, mabye..
Good luck & keep us updated..
