Know your cat!
I feel slightly guilty giving this a so-so review - the product seems to work perfectly, but it was a complete waste of money for us. The cat that is the main reason we got it - he's getting bullied out of his food - won't go near it. He is intimidated by the noise and hates having something over his head. He'd rather go hungry than use it. I should have known better! We'll have to try to sell it on, I guess.
