Love it
I decided we needed to buy a microchip cat feeder because I was fed up trying to stop my girl cat eating my boy cat's food all the time! She has also been told by the vet to loose weight where as he is a good weight.
I wasn't sure he'd use the feeder but I had no need to worry or use the training facility. My girl cat soon realised she can't get to the food in it so now doesn't even bother.
I want to write more but there's not enough space to do so. Buy it, you won't be disappointed.
