Hello, my first time on here! There's a stray cat (who I assume is a her) in my apartment complex that always comes by around the evening and I always leave a bowl of food and water out. I was hoping to get some advice with winter coming and how to aid in her survival with the cold. She is TNRed I believe because her ear is clipped. Sadly, I cannot bring her in because I live with my parents in an apartment with a cat and dog already, and they've already said no about getting another pet. But I want to do my best to help her. Anything more I can do aside giving food and water? Also, my mom told me to never pet strays because of fleas and other bugs. Sometimes it's hard to feed her because she is so friendly and tries to rub against my leg, and I get worried when she does. Is there any serious risks if she does, or is it not a big deal as long as I don't hold her or anything? Thank you for any advice!
