@Lilymoon my cat is free to roam whenever, I think it's different in the UK as we don't have many wild animals. The main worry is cars but I live in a quiet area. I think cats will usually try to avoid fighting if possible, it's all show and noise, they learn to not like getting their eyes scratched out.
@Lilymoon This might be true but I think they enjoy going out. My cat was a stray so she loves being out. I was hoping she would want to be an indoor cat but she wants to go out. She's up to date with flea treatment and boosters so I think the risk is worth it.
