Psyco cats tv show

Just watching a programme called 'my cat from hell' on animal planet. It's brilliant, cats hissing, biting and scratching their owners. It's psycho in kitty form.
A big bald bearded tattooed guy who is an animal behavioural goes to owners houses to calm the cats. He also has guitar case with him all the time for some reason (the man not the cat) I'm watching an episode with a huge cat called Mr Fluff, even I'm scared of this cat and it's on tv. Oh the guitar case has toys in it, ok...
