Yes some people feel comfortable around animals and some don't, true also for NTs. My dad was always a little bit afraid of dogs because he got bitten when he was a boy, and my mom didn't like cats, both got used to my animals (I have 2 dogs and 2 cats) tho and as long as they got to know them they were ok around them. It was actually funny how one of my cats used all his charm to get my mother to like him lol and he succeeded. Personally I love animals, I think they are much easier to "read" then humans, I usually know when they may be aggressive, but sometimes it is hard to tell, my rule #1 is to let them come to me, when I was a kid tho I didn't even have the rule #1 lol.
I wouldn't like being around wild animals like lions etc tho, I definitely wouldn't feel safe.
