Is my married coworker flirting with me or just being nice?

Ever since I started at my new job after orientation and relocated closer to work this woman around my age keeps starting conversation with me.
It is weird stuff like:
1. When we are listening to a podcast in the office she will ask me specifically what I'm listening too. One time I replied "Joe Rogan" and she followed with my husband love his podcast."
2. She also brought in brownies one day and brought me a plate with two before asking anyone else if they wanted any. The reason why she said she did this cause it was was the first time she made them since i worked there and wanted to make sure I could try some.
3. The weirdest one was I have an out of town tripwith a my manager and when asking someone to feed my cats inna company wide email she volunteered within a minute and mentioned it would work out cause she lives 40 minutes away from work while I live 5so it helps her commute. I never mentioned anyone had to stay and keep my cats company but she volunteered to stay at my apartment for 4 days.
4. Their is also compliments like she asked me what I use in my hair to make it so curly despite being a foot long, that she likes my shoes etc.
