I don't think she's coming into heat, it's too soon after her last one. and I kept promising myslef I would get her spayed but money's so tight right now. But I doubt it's that. she has stopped doing it. I did checke her glands, and there's nothing in there, all I feel are her bones LOL. maybe just her tummy was bothering her for those few days. She ate a whole lot the day before. I think she pooped like three times that next day.
Thanks for everyones input and concerns, I think she'll be alright now.
