If you’re in a pinch, I highly recommend getting dry food automatic dispensers (found some on Amazon for $80 each) and a furbo or some other interior camera that you can monitor them from. This recently saved us when we couldn’t find anyone to watch the cats for a weekend (obviously wouldn’t recommend any longer than 3-4 days max). We left out bowls of water all over the house in case any spilled and were able to feed them on their regular schedule directly from our phones. And we monitored the food to make sure it was working etc using the camera.
