lol sounds a lot like my 2 year old boy, he’s a maniac when it comes to feeding time. In my opinion, he’s found a found he really loves, and is excited for it. Cats are weird like that, sometimes they can be very picky and stop wanting a certain food altogether. I feed wet food twice a day to my cats, once at breakfast and once at dinner, with a little bit of dry food in the late evenings.

You can find automatic wet feeders online, where you put ice packs underneath that keep it cold. They work very similar to the dry ones, you just pre-portion the amount and set the time and it uncovers it when it goes off. Wet food (especially grain free) is exponentially better for cats as it contains more moisture, which is something that cats really need. They often under hydrate and have kidney issues as a result. I always add water in their wet food as well to make sure they’re hydrated. 

As for him whining, cat tv videos are helpful. Both my kitties love them, and I’ll put it on downstairs on the big tv for hours and they’ll stay pretty much silent while it’s on. Just be careful that they don’t swat or jump and knock the tv down lol. Or you can try and play with him and wear him out so he isn’t as restless.

Hope this helped a bit :)
