My Cat from Hell (2011)

Season 6: Episode 1

In the season premiere, newlyweds who both have cats bring them together under one roof, but one stalks and bullies its new sibling, which makes it pee all over the house. Meanwhile, a man's cat is so aggressive that his friends won't visit him, and the animal's diet of fried chicken, chips and doughnuts probably don't help its behavior.
