Help! I took in an abandoned young cat about 5 months ago and she had kittens at my place just before Christmas. The 2 kittens that survived seem healthy but they ventured outside last night for the first time and havent come back yet. they're only 5 weeks old. the mumma cat has come back home but didnt bring the kittens with her, she seems very anxious and keeps wanting me to come outside with her. she doesnt seem to know where they are either tho. i've poked around outside but i can't see them anywhere. It's been about 18hrs now. Should they come back when they're hungry? How far would they go? Can they find their way home?
