A couple of weeks ago my girlfriend brought home four kittens whom she had found abandoned on the street in a shoebox. They were cold and scared, barely 7-10 days old, as their eyes had only partially opened.
We took them in and fed them baby kitten formula bought from the store. (we don't have KMR here, I bought a brand called Vitakraft) They appeared to be okay mostly, with the exception of the smallest kitten who was constipated, cold and refused to eat - but I took her to the vet who fed her some glucose sub-q, after which she made a full recovery.
I thought everything was okay till last week when I noticed all of them eating less than the previous day. I monitor all of their weights and the amount they eat each time; sure enough they've been eating less and less for the past 4 days, and stagnating in weight. They're also more feeble and lethargic than before, one of them in particular, who now looks quite bad. Whereas before he was the most active one, he's refusing to eat anything and just sits alone, away from the others.
I took him to the vet today. He gave the kitten three shots (glucose, vitamins and an antibiotic) but he was pessimistic about the prognosis. In fact, he said that most hand-reared kittens don't make it because they eat formula instead of their mother's milk, making their immune systems very weak.
I'm worried that the four of them might have caught something and that they might all die. I'm thinking of taking them all to see the vet tonight, but short of giving them the same shots it seems like he can't do much. I'm not sure there's any way to diagnose whatever it is they may have - either that, or this vet has no idea what he's doing.
What should I do?
Thanks in advance for any answers and sorry for making my first post here so gloomy.
