Our volunteer stopped, and grabbed the crate (yes they are carried in all CHR vehicles) and proceeded to grab up all these tiny little kittens.
They were 6 total, all some form of LBK (Little Black Kitty). One very exotic colored silverback black kitty, who was very vocal. Our volunteers estimated that these kittens were around 5 weeks old. If they had been weaned, it was not very many days in the past.
We gave them CapStar (flea treatment) and our rescue food (Science Diet A/D). They were very obviously "wormy" so we applied ProFender (topical worm treatment). We try not to use the ProFender very often, because it is prohibitively expensive, but it is topical, and can be used on tiny little emaciated babies like this without harsh side effects that standard worm medicine has on the stomach.
They had no problem eating themselves silly, and then happily let us tuck them into their heated bed. They were taken to the vet the next morning.
Our Village Pet Hospital vet was happy to see that we had found them, and anxious to get them tested and vaccinated so we could release them from isolation into the Kitten Cabin.
Luckily these babies were simply abandoned, and not really in that bad of shape physically. It's normal for kittens to have worms (they usually inherit them from their Mom), but they were emaciated. Our vet guessed that they had been without real food (milk or otherwise) for about 3-4 days. Anything over a day can be a death sentence for a young kitten to go without food.
After their vet visit, we moved them into the Kitten Cabin, and liberally applied KMR 2nd Step, Royal Canin BabyCat, and Science Diet A/D. The combination of all these food items quickly brought the kittens back up to normal weight.
They have had 2 follow on vet visits, for their booster shots, and overall health check to ensure that the starvation did not cause any lasting negative effects. They are still not up to what we would like to see them weigh, but they are gaining weight every day.
