No, not yet. I suspected she was pregnant and was going to take her in this week, but she started to show signs of labor Friday morning so I didn't bother to make an appointment. I will definitely take her in this week if it's recommended, or at least call my vet about it.
She has pretty thick fur so I haven't seen anything moving, but I felt little kicks before and so did my sister when she came to visit. Now it's kind of hard to feel them unless I wait for a while but even then it's just little movements & I only feel them when I press my hand underneath her.
She's a little over a year, which I'm aware is pretty young, but she ran out about two months ago and I have seen a cat wandering around that I assumed was a tom because he was so big. But around that time she was out, my neighbor's male cat ran off as well & he isn't fixed.
Please see a vet to settle this question. It sounds like the cat is pregnant but not quite ready yet to give birth. A cat can experience pre-labor before actual labor as well.
