My husband lived in Vancouver BC and I here in State College PA when we met. When he came here to visit he would leave his cat Kaliban with one of those continuous feeders. The manager of the apartment complex would check on her every day and spend some time with her. Besides then he could watch hockey without the wife and kids around . Unfortunately he didn't understand that refilling it every day wasn't good for Kaliban. She gained quite a bit of weight which we are still having trouble getting off of her. She should weigh in at about 15 pounds or so. She is a big cat anyway..but right now she is at about 21 pounds. Ever try to get a 21 pound cat to exercise when she doesn't want to? You wave a string at her and she just rolls on her back and waves her paddle paws in the air at it. The best we have been able to do is to take her outside and Brian stands at one end of the driveway while I am at the other and we call her back and forth between us. After a bit she just gets fed up...lays down...flips over on her back and waves her paws at us But it is way cute.
