Ok, Filou went for his fluids today and there are some good news after he had a fallback 10 days ago . He gained 100 g of weight (approx. 1/4 lb) in the last week. He gets this by eating Royal Canin Renal dry food (good for him) and all kind of delicacies: egg yolk, ground beef, liver pate.
He is happy, friendly and very active- but he still has to be watched carefully or he will try to pee in the laundry basket. Maybe this basket needs a major cleaning orgy but I cannot do that before the weeekend. I don't smell anything but that doesn't mean he won't.
Don't stop your thoughts- it feels like a frail balance to me but it sure makes me happier.
