It has been some time since I watched this series but the one thing that I clearly remember is how stupid the people on it were. Some of them were antagonising their cat and then complaining when the cat objected by attacking them.
If you are fascinated by the working of the feline brain it is an interesting series. I don't think any humans were killed during the making of the programme. ☺
The typical problem seems to be - my cat attacks me if I do this to him (cuddle, pick them up or whatever) but I still continue to do it and then he attacks me again.
It's pretty obvious who the idiot in the relationship is.☺
