People like your FIL make my blood boil!! Living around this jerk must be almost impossible for you. Unfortunately, as much as we would like not to believe it, the world is full of ignorant morons like this. They're everywhere. All I can ever think of in cases like this is, "What goes around comes around". One day, hopefully, something will happen to him that makes him have to suffer just like the animals he so strongly dislikes and punishes. I hope and pray that you and hubby can get away from him asap. No animal lover deserves to have to tolerate such torture. Best of luck to you in getting out soon
