Thought it would be interesting to know about different cats’ reactions since it’s storm season right now. My big boy Nemo lived most of his first 2 years as an abandoned stray so he doesn’t get phased at all. My Skye has been an outdoor/indoor cat all her life until we adopted her from neighbors 1.5 years ago. She also doesn’t seem to mind. Benny was taken to a no-kill shelter with his siblings by a Good Samaritan at 3 months of age so he’s a different story. He is very curious about the outside world but also gets easily scared if outside. During a storm he gets nervous and can’t relax. He tends to be fearful of thunder and lightning. I guess it’s because he never had a chance to pick up street smarts (good!) like my other cats. He’s 4 now but it hasn’t gotten better with age so far.
