We found a very very young kitten at work.
Mother cat is no where to be found. We left it over night to see if she would come back but didnt.
And a heavy truck shop is no where for a cat to be alone.
Question is what has anyone fed one that they have found?
Hehe - this thread must have your head spinning.
Take to a vet asap and check for terminal issues and fleas. Fleas can cause anemia and kill quickly, terminal issues can spread to other pets, and might be treatable, or if not, they can kill quickly.
Kittens need HEAT more than FOOD if they've been abandoned. It's essential they get heat. A cat's internal temperature is 104. A hot-pad UNDER a plastic box (with a towel in the bottom of the box) is great when they're itty bitty - cover it over half way, and use a thermometer over the edge to monitor the temp inside. Check frequently.
I've nursed a lot of baby kittens (people just abandon them in boxes around where I live) - in the beginning, some didn't make it. Now, I have less issues when I have to do so.
Goats milk is ideal from a bottle. It's sold in cans at grocery stores. (advice from my vet)
You can litter box train them easily right after you feed them by rubbing their bellies and butts with a wet cloth - and then setting them down in the cat litter pan. A shallow aluminum foil pan works great - just sprinkle a thin layer in there, done. Works like a charm. This mimics a mom's bathing - is essential for them since they can't use the bathroom on their own like human babies.
They only need an all liquid diet for a short while (when compared to a human baby). When they get a little bigger you transition to milk out of a dish plus bottle feeding - keep up the litter-box rubbing/training.
After they can drink from the dish adequately, thin down pate cat food with the milk so they get used to eating solids. Provide milk for a liquid on the side. Maybe even a dish of water. They will drink both.
As they become used to eating solids their litter box training should be coming along really well.
Soon, they can drink liquids and eat more solid foods.
And, of course, play with them - they love to bite and love to claw all over you and everything else once they get big enough (doesn't take long) - so get soft toys.
