can I also suggest that with the kitten milk you send a kitten feeding bottle as I suspect John is currently reduced to either a syringe or to soaking cotton fabric for the kitten to suck. Am happy to pitch in financially as it is payday tomorrow, so someone PM me somewhere to send money. Also, perhaps a few small cans of kitten wet food to start weaning Lazarus when the time comes.
Some sterile wipes may also be useful, though I suspect John can get them where he is, but those medical supplies are for humans in dire conditions, so if we can provide them he won't have to raid local supplies.
Also maybe some puppy training pads to line the sling John may be using to keep the kitten with him during his day.
How exciting!!! Purrs to the Rescue Internationale!!!
