Do Not Rush Them To A Shelter Right Away
The first thing you should do is contact a rescue group or shelter if you see or find a stray cat, kitten, or kitten. Not all shelters are adapted to handle kittens, especially the feral ones. But at least they can give you further instructions and advice.
If you come across a new litter of newborn kittens, don’t touch them if you can help them. Do not take them to your local shelter on your own.
Many feral cats and kittens are euthanized because shelters and rescuers often do not have the resources to care for them. Always call ahead if you intend to leave them and get instructions on how to handle them carefully.
That said, kittens under four weeks of age are more likely to survive with their mother where you found them. Taking your kitten to the shelter at this stage may do more harm than good.
