Vacation and Wilbur

[culdesacfarm]

I have a potbelly pig names WIlbur. Our neighboor feeds him when were on vacation, but this year they are going on vacation the same time we are. I have someone coming over every day to check on the "farm" and give water. My problem is WIlbur gets fed 2 times a day. What happens if they forget and he does not get fed the whole day! I know Im a mother and I will be 5 hrs away and I want to make sure my baby boy will be ok! Any suggestions for an automatic homemade feeder??
