<human>: Can you condense the text into three sentences or less?

I brought my cats to the vet last week. They are a little over 2 years old.  The last vet visit they weighed in at about 13.2 lbs.  This year, one of them weighed in at 14.3 and the other weighed in at 13.8 - since they've put on a lot of weight in a year, the vet said they need to go on a diet.  

Currently they share about 2 5.5oz cans of wet food a day.  The vet had me just reduce their dry food intake by half, so they're sharing 1/4 cup of dry food a day sprinkled on their wet food whereas we would leave about a 1/2 cup out all night.

The 14-pounder has been okay with the diet - he just comes running every time he hears the treat bag or the can open.  The 13-pounder is very vocal, especially when the food bowl is empty.. we used to leave dry food out all night, but now we don't and he gets loud at 4am.  I've been trying to feed him later in the night so he can last until morning, but he still wakes up at 4 am every morning. 

I feel bad because I know he's just used to eating whenever he wants, but he's so vocal I feel like he's in pain or that I'm starving him.  It's only been a week. I'm hoping he'll settle down as he gets used to the new feeding schedule.
<bot>: My cats have gained weight over the past year.. vet suggested a diet. One chunkycat is not a happy camper.
