Originally Answered: Feeding my 2 cats equally (one eats faster and more than the other)
Thanks for your question and apologies for the delay in replying to you.
It can be difficult to feed two cats, especially when one cat tries to eat most of the food. You've mentioned that Clementine has a little belly, what's Plume's body condition like? I agree, I would also be worried that with one meal dispensed by an automatic feeder that Clementine would eat the majority of the food. This might lead her to gain weight, while Plume might not be getting enough calories and lose weight.
Would it be possible to have two automatic feeders, one for Clementine and one for Plume? That might be the easiest thing if Clementine tries to eat most of the food.
As Clementine eats fast, I'd also recommend a slow feeder bowl or an interactive feeder. It will slow her down when she eats and keep her occupied for longer. We have a lot of recommendations here;
I hope that helps,
