I'm sorry for your loss.I tried to put the little one out of her misery last night, but I stood there with her for half an hour and just couldn't bring myself to do it. She died during the night, at least she's not suffering any more.
The other one is lonely now but still doing well. She seems to be doing fine, but I'm scared she's not really strong enough to go back outside, as last time she almost died. So for now I'm keeping her inside and taking her outside for some fresh air and sunshine under supervision. As soon as she's eating more reliably and looks less scruffy I'll try and put her outside again.
The 3rd one has survived 2 nights outside now and seems to be completely recovered. It fell behind the others in size a bit but I'm sure it'll catch up soon.
I'm glad to hear #2 is still hanging in there. Giving her a few more days of supportive care will hopefully have her strong enough to join the others soon.
Sounds like #3 is doing well! Even if they fall behind from being sick, they usually catch up fairly quickly.
Thank you for the update. Just know you have done everything that you can for them - you've done a good job.
