I've been feeding several feral cats for the past 6 months. I put food out each day at the back of my driveway. The problem is I will be traveling out of town every other week for the next couple months and I was wondering how I can make sure the cats are fed while I am away? I don't have anyone who can help. I was looking for large feeders online but not sure if this would work or if there is one large enough to do the trick for a week at a time. Any help appreciated. Thanks
