That's not enough to ensure that an intact male doesn't get to her. It's for her own health that she should be kept 100% inside while pregnant and nursing. You want to be sure that nothing happens to her, and that she delivers inside somewhere safe where you can help.She is almost 2 years old and I also have a stray neutered male in my house who keeps the territory safe stray males away from the house.he also keeps her safe when she is in heat that’s why I didn’t got her spayed.
Can you keep a sharp eye on the litter box? Try a little plain pumpkin - not too much just a part of a teaspoon but that can sometimes help, or some hairball gel. Do you have a vet you can talk to? Maybe this will help regarding whether she's pregnant;N haven’t pooped since yesterday
