Gill I’m so sorry that your dad lets her out:( my parents used to do that when my cat was younger and I would be at school. My cat is now 5 and I keep her inside all the time because I think it’s dangerous and she has been inside so long that she wouldn’t probably do great. Maybe try telling your father how concerned it makes you? That’s what I did with my parents it took awhile but they don’t put her outside anymore!
