Most of the time, the kindest thing you can do for a kitten is leave it where it is. Mom is usually nearby, and a working mama cat is hard to beat. The questions below are based on guidance from groups like Alley Cat Allies, Best Friends, the ASPCA, and Kitten Lady. They're meant to help you think through the situation, not replace advice from a vet or local rescue.
Some signs people watch for: bleeding, open wounds, labored breathing, runny or crusted eyes, lethargy, flies or maggots, bodies that feel cold to the touch, or a kitten that isn't moving. When you're unsure, most rescues suggest treating it as urgent.
These are rough guidelines that show up across most rescue resources. Real kittens don't always fit neatly into a bucket. When in doubt, most experts suggest guessing younger, since that advice errs on the side of caution.
Eyes closed or just opening
Tiny, ear-flaps folded, can't walk. Needs mom or bottle every 2 to 3 hours. Eyes start opening around day 7 to 10.
Eyes open, wobbly walking
Eyes fully open, ears unfolding, starting to toddle. Still nursing every 3 to 4 hours. Not eating solids yet.
Mobile, talkative, tasting food
Running, playing, starting on wet food alongside nursing. Curious but still small.
Playful, 1 to 2 lbs, eating on their own
Fully weaned or nearly so. Using a litter box. Approaching spay/neuter weight.
Active, playful, 2+ lbs
Don't need mom. Ready for spay/neuter.
These are the points most rescue organizations come back to again and again, but your local rescue or vet always knows your specific situation best.
Multiple sources (Alley Cat Allies, Best Friends, ASPCA) note that most kittens brought in as abandoned actually had a mom nearby. She may have been hunting, eating, or moving the litter one at a time. Watching from a real distance for several hours is what most groups suggest before stepping in.
Most rescue organizations caution that cow's milk can cause diarrhea and dehydration in young kittens. Kitten formula (KMR) is the typical recommendation; check with a vet or rescue if you're not sure what's safe.
Many rescue groups note that a kitten that feels cold often shouldn't be fed until they're warmed up. Body heat, a low heating pad under half the carrier, or a warm (not hot) water bottle wrapped in a towel are common approaches.
Most sources suggest keeping littermates together when possible. They help regulate each other's body temperature and tend to be less stressed than when separated.
For unweaned kittens specifically, organizations like Best Friends point out that an under-resourced shelter without 24/7 bottle-feeding can be riskier than the spot they were found. A foster-based rescue is often suggested as a better landing place.
Most rescue and TNR groups emphasize that helping mom get spayed is one of the highest-impact things a finder can do. One unspayed female can mean another litter, or several, within a year.

Not professional advice. Pawsitive Foster shares this as a general educational resource. It isn't veterinary, behavioral, or legal advice, and it doesn't replace guidance from a vet, a licensed rescue, or your local animal services. When in doubt, especially with sick, injured, or very young kittens, please reach out to a qualified rescue or veterinarian.
Connecting with a local rescue is the fastest way to get a real answer for your specific situation. Most are happy to give phone or text guidance even if they can't take the kittens.
