"Fantastic! My cat Luigi was seriously overweight and has a chronic urinary problem from over eating on dry food, he has cost me well over £1000 at the vets due to repeated catheterisations. A wet food only diet seems to have resolved this problem but he is a dry food addict and will steal the food that is left for another cat Mario (because Mario won't eat wet food). I thought the feeder was a bit pricey but it is worth it to save on potential future vets bill. It was really easy to set up and use, although we did use the learning mode for a few days. Luigi is now losing the rest of the weight he needed to lose and is so much healthier. Also my other cat Scared is overweight and now he can't get at the biscuits either! And we don't have to keep watching all the time. And the feeder looks good too - very stylish."
