Hi Bob, AFIK there is a "social" problem with this auto feeding device. Genetically cats can not be trained (like dogs) to do "interesting " things for their owners, so the feeding process is just a feedback reflex, something that Pavlov demonstrated back in 1900 ( http://www.simplypsychology.org/pavlov.html). Being so, the feeding process should imply a higher interaction between a human and his/her cat. For example my tomcat was weaned too early. As a common behavior in such situations, it bites me all the time I pet him. It's not a bad bite, for him it looks probably friendly, but it's a bite. I do not feed him since I'm not at home. The cat feels that it's owner is the person who feed it. His/her behavior is different with the other members of the family. This is what I called the "social" problem. best luck with the device, Vasile This email has been sent from a virus-free computer protected by Avast. www.avast.com <#DDB4FAA8-2DD7-40BB-A1B8-4E2AA1F9FDF2> On Mon, Dec 28, 2015 at 12:38 AM, Bob Blick wrote: > On Sun, Dec 27, 2015, at 01:51 PM, John Ferrell wrote: > > > FWIW: Are youi OK Bob? you usually cut me off before now. > > I think I'm OK :) Nothing I've seen has been overly offensive, and > although I have been pushing/pulling the levers of power it's been > behind the scenes.
