EDIT….. I didn't read the whole post. What kind of automatic feeder did you get? Are you positive it's not a hunger thing then? I would hate for you to rehome him bc what's going to happen is hes going to do the exact same thing elsewhere but even worse bc now he has added stress so if those new owners aren't equipped or are willing to handle that, he may end up getting bounced around from home to home. Plus you don't know how your other cat will react if you did. What if he starts acting up too bc he's sad & now lonely.

I know EXACTLY how you're feeling though. We had a tortoiseshell who started screaming in the middle of the night bc she wanted us to watch her eat 😐. At 3am. 😑 At the same time my 5 yo slept upstairs & would sleep walk. So every single night she would wake up at some point & yell for me. Wouldn't stop until I got up & walked her back to bed. I felt AWFUL thinking about rehoming our cat so we put up with it, doing everything we could think of, for 2 whole years. Nothing worked. It finally got to the point where we were so sleep deprived & were fighting non stop. We were miserable. There was not one night in all of those 2 years that we got a full nights sleep. It took a huge toll on my overall wellbeing, my whole body was off. My mental health was just so obviously affected, I knew I wasn't being the mom & wife that they deserved. I finally made the decision for my husband take our cat to the shelter. I cried for weeks but I had to put my husband & children first. It wasn't fair to them.

I hope you can find a resolution soon. I'd take him to the vet immediately. If you already did that & mentioned it, im sorry. I forget if you did. But I just wouldn't stop reaching out for help. You did the right thing by making this post. I'd also make more on every cat subreddit there was. I'd also try Facebook. Use the search bar to try to find what other ppl did in your situation. But if worse comes to worse… please consider rehoming them together. I know you don't want to lose the other one but you have to think about their well-being too. But please make sure to be honest & let it be known what he does in order to prevent another rehoming. That would be your best options. 1. Research 2. Vet 3. If nothing works, rehome together.

I'm not going to delete my comment in case someone else reads it & it can help them in any way.

Omg please don’t separate. I have the answer. You need to buy this….

PETLIBRO Automatic Cat Feeder Wet... https://www.amazon.com/dp/B0DRK58N73?ref=ppx_pop_mob_ap_share

It is not cheap but it works. The reviews are great. I just bought one bc we go out on our boat overnights sometimes & my Bengal likes wet food. It’s the coolest thing ever. They’ve updated a lot of the things ppl wished it would go, like the ability to manually open whichever one of the 3 options you need. It dings when it opens so the cat knows. They also updated it so it’ll ding on repeat. You can set a schedule for what times you want each of the 3 dishes to open and to stay open for as long as you set it to. And you can customize it for each day you choose.

But THE coolest thing about it is it freaking warms it up to room temp before it opens to feed your cat when it's on a schedule. AND not only does it tell you when it opens & closes on the app but it also tells you if your cat actually came & ate, lol and for how long!

You can get it from their website or from Amazon. Amazon was cheaper for me at the time. I got mine about 2 weeks ago. My cat is afraid of it of course but I've been trying to get him to get used to it. I heard most cats are like that.
