This automatic feeder can hold up to 12 meals depending on the size of each portion (you can choose from 1/8 cup to 4 cups).
"My PetSafe automatic feeder allows me to sleep in peace without my cat nagging me, travel for up to four days, and controls the food amount." —caroline5
"Our cat is fat. Her life is pretty much driven by food and the only way we've been able to keep her at a moderately sustainable weight is by giving her healthy food she hates and this pet feeder. Every time we come back from a trip, there are a few more claw and bite marks on it, but it holds strong. She's even tried to sit on it, but it's done nothing more than presumably horrify it a little. She used to move around the bowl so when feeding time came she could put her head where the chute is and feel the food rain down her head like Augustus Gloop in the chocolate factory. I would recommend this for anyone who has a cat who is consumed with eating and getting food. Her persistence has defeated every other one we have tried. Yes it is expensive. Yes it is absolutely worth it." —BMoney
