Wait and Watch
Always wait several hours, or even a full day to see if a mother cat returns. Watch from a hidden spot or from inside so you don’t scare the mother cat away. Your presence may keep her from returning to her kittens’ nest.
Even if you don’t see the mother cat for a long time, check on the kittens periodically. If they are cuddled together and sleeping quietly, look pink, warm, and clean, and have full bellies, then their mother has very likely been back. You just didn’t notice. Community cats are good at staying out of sight when they want!
A Helpful Tip
Sprinkle flour near the kittens’ nest. If the mother cat returns, she will leave paw prints.
If you have waited for several hours or more than a day and have reason to believe the kittens’ mother is no longer around, step in to help them. Neonatal kittens (kittens 4 weeks old and younger) will need special supplies and round-the-clock care to survive.
