Query: Useless for cats and could be dangerous!

I can't imagine that there is a cat on this planet that couldn't defeat this "protective" collar in seconds. It folds down, and as soon as the cat realizes that, they will fold it down themselves! Maybe there are dogs that can't figure it out. It is made out of very cheap noisy opaque plastic (blocks her view completely) and closes with a string (Dangerous for cats!). I tried it out because my cat was getting surgery and I wanted an alternative to the big plastic cones that the Vets use. Well the Vet made a custom made cone for my cat that fit her perfectly. It was made out of a high quality lightweight CLEAR plastic that allows her to see all around. It is cushioned by her neck and closes with strong Velcro. Yes she hates it, but it is safe and it really does the job of protecting her without putting her in danger.
