My dad and his gf live together. One cat was a stray that the previous owners left behind that my dad takes care of. The other one is my dads gfs 3 years old cat. They both stay outside during the day and come in at night. My dad and his gf are going to arizona in a couple days and they were just gonna leave the cats outside to fend for themselves. I thought that sounded crazy. My dad said they'll be fine because they are good at catching mice and birds and they can drink from a nearby stream. I know this is wrong. What should I do? Should I call animal control? I dont want to ruin my relationship with my dad over this.
