I hope tomorrow's Vet visit with Belle goes o.k.
Oscar had a very bad Gastric bug a couple of weeks back, and I was watching him almost around the clock for 6 days. At the outset ( and before we got the results of the ultra-sound , and blood tests ) It was looking like I would lose him , as organ failure had not yet been ruled out. Like you, I was beside myself with worry. I mention all that, because anti-biotics and round the clock T.L.C brought him back to the land of the living. I would thus hope Belle will also be 'turned round' - due to your loving vigilance in noticing her plight.
The thought of Amelie calling for you when you are not in sight is also touching. :) Even at 12 years old Oscar ( as did his previous house mates ) always shouts down the steps after a sleep - and 'Squeaks' in a charmingly girly voice when he wants a wrestling game . The fact that they feel so bonded and safely integrated into our lives , is a great treasure to behold. I saved mine once, and they saved me 1,000 times. :D
Please let us know about Belle, ; I will keep an eye on the forum for the update.
