Im so sorry to hear of your boys recent relapse OP, you're in my thoughts at the moment and I'm keeping everything crossed he starts to improve.
What a rollercoaster of emotions you must be going through
He's still with us for now and we're starting today to try to reintroduce food again very slowly. We're basically back where we were on Monday but with a stronger concern that his guts can't cope with enough food to sustain him. My mum's little cat also went missing on Thursday whilst George was colicking and she reminded me this morning that Thursday would also have been her wedding anniversary if we hadn't lost my dad. All round, a very bad day. She's gone to pieces so I'm packing her off on holiday tomorrow. I feel like i've been through the wringer about 10 times.
I really feel for you best of luck to George, have been checking regularly to see how he's doing, hope his tummy manages the food well today. Positive thoughts.
ooh you poor thing, do try and look after yourself (I know easier said than done in the circumstances). Sending tons of vibes for both you and George xxxx
