I have a 11lb 1 year old. Had to take him to the pet urgent care for something else, vet said he was minimally dehydrated after seeing his eyes. No skin tent. Morning, he gets half a can of friskies with half of a 1/4 cup of dry. Same for dinner. The wet has 82% moisture. Since the vet visit, I have added water to his food, about a tbs per meal, so 2 tbs extra water a day. It's been a while since I've seen him drinking, maybe right before the vet visit (friday). His eyes still look sunken in despite the 100mls of fluids they gave him that day, no skin tent either. He eats, plays, still have zooming, all normal. I ordered a fountain so I'm hoping he likes it. I'm wondering based off of that, how much water is he still lacking? He has a appt on the 8th but till then I'm just curious
