Yes, I know I have been on here multiple times, but I have another question. So, I heard a hissing sound and my cat was in the bathroom with my ducks, so I immediately thought that my cat was hissing at my ducks. I went in there and started to investigate. I was so shocked when I heard a hissing/deep breathing sound from one of my ducks. So, to answer my question, is my duck hissing at my cat!? I know ducks hiss, but I've never heard mine do so.
