We took in a stray last winter, and didn't have the funds (and still don't) to get her spayed. As hard as we tried to keep her in, she got out, and BOOM, pregnant.
She had the babies in July, and we kept two out of the four babies. I don't remember when she stopped nursing, probably late September (it went on forever!).
She never seemed to go back into heat, and still isn't. Her mood was really unusual for her until, honestly, this past weekend. Only then did she sort of snap back to her normal self, which we figured was because of hormones and a respiratory infection she had.
The weird thing is, she's got a big belly that sort of looks like a pregnant belly.
A little bit worried...could she be pregnant again? I know there's no way to know for sure unless we take her in, but the fact that she never went back into heat seems weird.
