I bought this product almost 6 months ago now and it started off working great, but now I'm having constant problems with it not dispensing food in the proper amount - sometimes it even skips meals! I bought this product for my overweight cat to help to control how much he eats, but I don't want him to miss meals completely! I thought it would be useful to have something that could feed him while i went away for the weekend, but now I don't trust this machine to feed my cat properly. If I could get a refund I would.
