3 days later her stomach gained about 4 inches (11cm) more water, we took her to another vet, he withdrew clean water
out of her belly and
said she might have a underdeveloped liver. The vet wanted to put her down, but I refused that. Got her on meds, but had to drain the belly when it reached 33.5 inches (84cm) with 1.57 gallons of water, that's 7.1 liters. It went well for about 2 weeks now, but now she doesn't want to eat, she's pick up some inches and then drops again.
