首先你馬上報警.這樣She had police visit, NOT you. Now you had police visit due to your improper action of keeping wild animals on your property. Then you can contact the landlord. Now you're at fault due to your "inaction." The owner has nothing to back to evict them because you're at fault in the first place.
不要給野生動物喂食.要貓按正當手序弄一個.
"我們並不想花時間和精力在這種事情上" 沒有辦法,this is your priority now. 找個律師,如果不想花時間和精力.
The laywer will first nail her for medical report. Then he/she will need evidence from the animal shelter on that cat's medical examination.
But you could've done better and easier:
1. have police record on that incident
2. Find owner from your county assessor.Press her/him for eviction.
