I'm going to get crucified but I think cats are just another human driven ecological disaster. If you own a cat you should have to keep it inside. 1) If it's outside and has a collar you get a heavy fine 2) No collar - euthanize Why is ok to let a cat kill wild animals?
We can't eradicate feral cats. If you kill all the cats in this colony, new ones will move in. Depopulation doesn't work for this type of situation. Improving vaccine coverage and human interactions will be more effective.
Why don't we have wild dog packs roaming around?
And spread disease!
