Same for small kittens. If you find a bunch of little kittens in your yard please leave them alone. Don’t whisk them away to your nearest shelter or rescue group. Most of the time the kittens will end up being put down. If you must do something, put some water out for the mother (but not food, food will attract predators) at a safe distance that the kittens don’t wind up in it. The mother will come back for them. Now, if you know or have reason to suspect the mother is dead then you can take them in.
...nah seriously I always stay as far away from babies as I can.
