There is a relatively new bruiser of a cat in the neighbourhood who is bullying our cat. This evening there was a standoff with our cat under a patio chair and the bruiser just a metre away. One of them was making a very deep sound over c.7 minutes. I thought it was a power tool but assume this was actually bruiser cat. It took me quite a lot of effort to shoo the cat away.
Is there anything I can do to make the bruiser not come in our garden or hassle our cat?
