Sigmund is Sick
Siggy didn't eat for 24 hours so I took him to the vet again this morning. Diagnosis: infection in the GI tract. Prognosis: Not good. Siggy is very little and very sick. Not a promising combination.
His energy level has dwindled over the last day or two, and now he is sleeping almost all the time. The only positive indication we've had lately is that we did manage to get him to eat something at the vet's, and he had a few small bites just now.
The vet gave him an infusion against dehydration, and said that it's not uncommon for young street cats to simply be too fragile to withstand being abandoned by their mother; only when they've lived for 2 months can you be reasonably sure that this is a sturdy cat. He said to keep giving him small amounts to eat (of his special new sick-kitty food, mixed with a teeny bit of water) every few hours, and hope for the best. If he makes it for another few days, it will be a good sign.
