There's a cat that has been coming into our garden and even our house occasionally and frightening our two young cats. They are getting braver at hissing at him but he still dominates them and we think has sprayed scent on them. Today while I was out DP found this cat in the house so shut him in, chased him around shouting at him, then put him in a bath of cold water, all to frighten him off. He'd mentioned before that he was panning to do this and I asked him not to, because it seems really cruel and excessive and also I thought about how I'd feel if someone did that to one of ours..he's an aggressive cat yes but just doing what some cats do. My question really isn't whether he was unreasonable to do it, because I think he was and have told him so..but I'm feeling really uncomfortable that he could do this at all, even though he believes it was right to defend our young cats that way...I feel a bit creeped out by it. Am I being soft and should I be grateful on our cats behalf? I was hoping they'd just eventually be able to defend themselves.
