Shocking and horrible as this is, a cat has at least the option of running out of an open door, or jumping out a window and finding a new home for itself.
Having said that, I remembered our "rescue cats" - the female had found an open window and jumped out of their abusive owner's home, but as she could not persuade her brother to follow her, she jumped back in, and put up with the abuse, until they were rescued.
This man's child does not - or not anything like as easily.
Unfortunately, I doubt social services will deem him an unfit father on the basis of a video showing his gross cruelty to the cat.
