There are a few things to consider when wondering if two cats can share an automatic feeder. The first is the size of the feeder. If the feeder is too small, it might not have enough room for food for both cats. The second thing to consider is whether or not the feeder has a timer. If it does, you'll need to make sure that it's set for twice the amount of time as you would for one cat so that each cat gets their fair share of food. The last thing to consider is how much your cats eat. If one cat eats significantly more than the other, you might need to get a separate feeder for each cat so that they can both eat their fill.
All in all, two cats can share an automatic feeder as long as you take into consideration the size of the feeder, whether or not it has a timer, and how much each cat eats. By keeping these things in mind, you can make sure that both of your furry friends are getting the food they need!
