We've had a pregnant stray hanging around for a little over a month now. We've been feeding her and provided a crate in the garage hoping she would opt to have the kittens in there. She's very friendly and loves all the attentions she's been getting.

Today, we ddn't see her for most of the day and when she came by about 7:00 pm I think she looks a bit thinner, but still plump. IS there a way to tell if she had the kittens while away today? I'm going to see if she wanders away and try and follow her, but don't know if I'll be able to. Will a cat leave her kittens? We know she's had at least 1 litter before this one. Her nipples have been enlarged from the day she started hanging around.

TIA!
