I have three indoor cats. try talking to all the neighbors with dogs and tell them they all must put forth some money because they are all guilty. stress your Mom's age and financial situation and the law too if necessary. good luck hon. after this, Tom should remain inside. poor cat. i hope he gets well soon.
i lost my 17 yr old cat to an attack by a fox or coyote at 2 a.m. when my hubby let him outside for a potty break. for some reason he refused to use his indoor potty anymore. His injuries were too bad and he was put to sleep. I still miss him even though we now have three indoor cats!
