Apparently, the genuine (more expensive) catlock seems to have a flaw compared to the low cost versions - they have a couple weak points around the screws.
Now, I doubt my £200 genuine catlow was what I thought, what I actually need. Too late now, I will be praying that it will deter the low skilled chaps attempting to get my cat.
