Query: Many improvements over our older model

We had a 9 year old model of the same feeder and wanted to upgrade primarily because of the shoot that doesn't allow our cat to pick the food out of the opening. Other improvements include 1) a more rounded bottom to the bowl, the older model had a sharp angle making it difficult for our cat to get food out of the angle formed by the bottom and side of the bowl. 2) Screw on lid 3) more granular timer - now supports seconds instead of just minutes allowing us to feed smaller portions more times a day. 3) timer has an outlet on it allowing you to string together another device such as a water fountain. Only complaint is it is still cumbersome to take apart to clean.
