Hi, I am taking care of few stray cats, basic things like feeding them, rubbing their bellies and so on. However something strange happened like 2 weeks ago. One of them came back home (they are not living inside) and she had her fur on cheek ripped off, really scary. And today I found out that other 2 cats have something similar on their necks. What should I do? I cant take them inside but also I cant hunt down the beast that is trying to kill them. I assume that it is some wild animal cuz I live in rural area.
