Sadly my cat Porker is blind and old so his skills are not up to snuff.
Yeah that was my sister's cat Lucky with Porker they fought whenever they came in contact with the other. However my sister like the sister she is just brought her cat into our house without introducing Porker, Spud, and Lucky to each other in a separate location. So Lucky was invading their territory uninvited by them and they acted accordingly. So usually I had to rotate Lucky and Spud as Porker was outside usually. Lucky was locked in my sister's room when Spud got to roam the house and then Spud was locked up in my parents room when he was out. It was very annoying to round up the cats and a few times Porker was hiding and I thought he was out so Lucky and Porker got into a fight.
