Is it a brown widow? Or a non-poisonous spider?

I have some yards cat and at night I put them in a pen and anyway there are alot of baby spiders. I saw the mom and she was a dark brown color and had stripes on her legs but I looked hard and I didn't see an hour glass. When she's curled up, she is as small as my pinky nail. Then the babies are like a gold/brown color. I definately know it isn't a brown recluse. But could it be a brown widow? Oh and please send me a picture of baby brown widows please! Thanks in advance
